The clip comes from Team Fortress 2, Valve's class-based shooter released in 2007, where the Scout is the fast-talking Boston runner voiced by Nathan Vetterlein. Taunts are built-in voice lines each class uses against rivals, and Scout versus Scout lines became especially popular in community videos and soundboards. The 'pootis' tag reflects the wider TF2 meme culture around Heavy and in-game voice spam. Fans still share this taunt in edits and streams because it captures the game's humor and competitive banter in a few seconds.
