>>1785999Waha~ (No, not the amateur hockey league) is a cute anime girl (see Moe ) that was widely prevalent on 2chan and 4chan’s /b/ and /jp/ boards.
Encyclopedia Dramatica depicts her as an “Old Meme” .
Origin:
While becoming popular on 2chan, and then crossing over to 4chan, Waha~ is a fanart image of a character named ‘Suzuran’ from a hentai game called ‘Suigetsu’. The reason she is called ‘Waha~’ is because she yelled it out after every one of her lines in the game.
