Team Fortress 2, Valve's team-based shooter released in 2007, is famous for its larger-than-life mercenaries and quotable voice lines, and short taunts like this one have long been clipped by players for use outside matches. The your mother line works because it is a universally understood playground insult delivered in the game's exaggerated style, so it translates easily to reaction videos, edits and Discord jokes. As TF2 remains a staple of gaming meme culture, the clip continues to circulate on soundboards and in montages where a quick, familiar roast is needed.
