TimTheTatman, real name Timothy Betar, is a longtime Twitch streamer known for variety gaming, loud reactions, and laid-back trash talk with friends. Short voice lines like this one get clipped by viewers and shared as reaction sounds because his delivery is instantly recognizable to gaming audiences. At just over two seconds, maybe your ass works as a quick sarcastic shutdown, which is why it circulates in gaming edits, Discord soundboards, and meme compilations rather than as a standalone catchphrase.
