Asterix began as a French comic created by René Goscinny and Albert Uderzo in 1959, following a clever Gaulish warrior in Roman-occupied Gaul, and the character later reached wider audiences through animated films and television adaptations. The exaggerated yoo-hoo greeting fits that cartoon world of expressive voices and quick visual gags. Online, short cartoon calls like this one are clipped and reused as reaction sounds, which helped this greeting circulate on soundboards and in meme edits long after the original animations first aired.
