look up any word, like wcw:
Suffix; no true meaning, though when added to practically anything, it's almost guaranteed to sound (more) Japanese.
Use frequently with common "otaku" lingo and bad grammar, along with random Asian-sounding noises, and you'll sound genuinely Wapanese!
Sounds best when used with a squeaky, annoying voice.
