Rocket Raccoon is the sharp-tongued, genetically engineered raccoon from Marvel's Guardians of the Galaxy films, voiced by Bradley Cooper. His deadpan humour and love of chaotic plans made him a breakout character after the first film in 2014. Short lines like this one were clipped, looped and shared across meme pages and soundboards, where the extended version gained traction because it works as a complete reaction on its own. It remains popular in edits because Rocket's voice is instantly recognisable and the cheer fits almost any triumphant moment.
