The 'Is That a Pro Genji?' meme originated from a 2016 YouTube video by the gaming personality VideogameDunkey titled 'I'm Moving to Team Fortress 2.' In the video, Dunkey sarcastically reacts to a player choosing Genji in Overwatch, exclaiming the line with exaggerated, feigned amazement. The phrase quickly became a staple in the gaming community, used to mock players who believe they are highly skilled or to ironically celebrate mediocre plays. Over time, it evolved beyond Overwatch, becoming a general catchphrase for any situation where someone is perceived as trying too hard or displaying 'pro' level behavior in a humorous or cringe-worthy context.
