Bakka !

BAKA!!

That's my favorite word, probably because I relate to it so well. I'm such a baka! (I thought it only had 1 k, though. That's how I've always seen it used.)

[ps, for all you reading this who have no clue what "baka" is, it means idiot.]

Actually, should be only one 'k', as in 'baka', (if it is the word I believe you are wanting to use).

A good addition to that is 'baka yaro!', or as they say (insult) in the Kansai area in Osaka: "aho!" (pronounced the same as the southern Arizona town of "Ajo")
