Sketch

From Football Field to Streamer

Kylie Cox was born in Houston, Texas, and attended The Woodlands Christian Academy, where he played linebacker for the school's football team. His athletic pursuits continued as he enrolled at Mississippi State University before transferring to several other institutions, including the University of Oklahoma and Texas State University. He ultimately attended Lone Star College before deciding to leave academics without completing a degree.

Before his streaming career took off, Cox worked in real estate from 2020 to 2023. This period of his life preceded a significant personal and professional transformation that would later become public knowledge. His background in sports and business provided a foundation for the content he would later create, focusing on the strategic and competitive aspects of sports video games.

Building a Streaming Career

Sketch began his online career in 2023 by streaming gameplay of Madden NFL 24 on TikTok. He quickly expanded his presence, starting to dual-stream on both TikTok and Twitch in July of that year. By November 2023, he had launched a YouTube channel, where he posted Madden gameplay and vlog-style videos, establishing the core of his content.

His early focus on a popular American football video game set him apart in the streaming landscape. This niche allowed him to connect with a specific audience of sports and gaming fans, a community that would grow exponentially in the following year as his personality and catchphrase broke into the mainstream. His content strategy from the start involved leveraging multiple platforms to maximize his reach and audience engagement.

The Viral 'What's up, brother?' Phenomenon

The phrase that defined Sketch's rise to fame originated during a FaceTime call with fellow streamer Jynxzi, whose real name is Nicholas Stewart. When Stewart called him during a live stream, Cox replied with What's up, brother, while pointing his index finger upward. This simple interaction became the seed of a massive trend.

In 2024, the catchphrase went viral on TikTok through a trend where women would say the line to their boyfriends while making the finger gesture. The men's reactions, which ranged from confusion to enthusiastically repeating the phrase or saying Tuesday, Tuesday, fueled the trend's popularity. It spread to professional sports, with teams like the Dallas Mavericks, Tennessee Titans, and the NFL itself incorporating it. Players such as Bryce Harper, Johan Rojas, Bo Naylor, and Kyle Tucker were seen doing the celebration. By the end of the year, Twitch officially named What's up, brother the catchphrase of the year in its 2024 recap, confirming its place in internet culture.

Crossover into Mainstream and Sports

Sketch's popularity led to significant collaborations with major brands and sports entities. In April 2024, the Houston Texans revealed he would announce one of their NFL draft picks, a role he fulfilled on April 27 by announcing the selection of Cade Stover with the 123rd pick. This moment symbolized his acceptance into the professional sports world. He later participated in the AT&T Annihilator Cup gaming tournament and appeared in the official trailer for Fortnite Reload in June 2024.

His crossover appeal was further demonstrated through high-profile charity soccer matches. In June 2024, he played goalkeeper for Team AMP in a match organized by Beta Squad and AMP at Selhurst Park in London, an event that raised money for The Water Project. The match ended in a 6-6 draw after a pitch invasion. In March 2025, he played the same position for the YouTube Allstars in the Sidemen Charity Match at a sold-out Wembley Stadium in front of 90,000 fans, making a crucial penalty save and being voted player of the match. The event raised money for BBC Children in Need, Bright Side and M7 Education.

Further collaborations included appearing in an advertisement for Sidemen's Best Cereal in July 2024 and participating in a MrBeast video titled 50 YouTubers Fight for $1,000,000 on July 13. He has also been involved in various golf content online and participated in the inaugural Internet Invitational organized by Barstool Sports.

Awards, Recognition, and Personal Challenges

By late 2024, Sketch's impact was formally recognized within the streaming industry. Complex Networks ranked him 14th on its list of the 25 best streamers, while Dexerto placed him fifth on its list of the 10 best streamers of 2024. At the 2024 Streamer Awards, he won the award for Best Sports Streamer and was nominated for Best Breakout Streamer, highlighting both his niche expertise and his rapid ascent.

In July 2024, a YouTuber named Pocketbook posted a video alleging that before his streaming success, Cox had created content for OnlyFans under the username Jamie Mar. He addressed the rumors directly on a Twitch stream the next day, confirming his past involvement and explaining he was going through a rough patch and dealing with addiction during that period of his life. He stated the videos were from two years prior and that he was a changed person. During the stream, he made light of the situation with jokes, including a reference to a Bill Clinton quote from the Clinton Lewinsky scandal. The incident sparked homophobic and anti sex work backlash from some, but also prompted a wave of support from multiple other social media personalities and athletes.

Content, Community, and Personal Life

Beyond his viral moments, Sketch maintains a consistent presence across multiple platforms. He continues to stream on Twitch and create content for YouTube and TikTok, where he has millions of followers. His content often revolves around gaming, particularly Madden NFL, and his interactions with other streamers and his community. He has also engaged in collaborative projects, such as working with other creators on content like Streamer University.

A resident of Houston, Texas, he remains a vocal supporter of the Houston Texans, often blending his fandom with his streaming persona to create relatable content for his audience. His business inquiries are handled through a dedicated email, and his content strategy includes making certain videos, like an episode of Beast Games, copyright free to encourage other streamers to react to it, fostering a sense of community within the creator ecosystem.
