No reliable source documents who recorded this shout or where it first appeared, so its history is in how it travels as a short named clip on soundboards and in meme edits. The Spanish word pedo, slang for a fart and for a messy situation, gives the one word instant crude humour for Spanish speaking audiences and beyond. Its sub second length makes it easy to drop into chats, remixes and reaction videos without explanation, and that repeatable, context free use is why the shout keeps resurfacing.
