The quick version of the Spoo thing is this: Okasan to Ishho is a kids show in Japan, upon which cute hostette Shoko Haida drew an ungodly version of "Spu", one of the plushie characters on the show. Her version is the stuff of nightmares; imagine a Barney the Purple Dinosaur with Jaws teeth and Cthulhu tentacles and say a giant cock. The Futaba Channel boards (2chan) picked up on the sketch, and it has become a meme of sorts, like a blend of the ORLY? Owl and Domokun. Info via both Avoiding Life and Mari, both of who go into some details we omitted to keep things snappy.
