Japanese for "idiot". Often mispronounced by white anime-obsessed college kids who insist on using it in conversation but instead utter a less-than-enearing "BOCK-uh".
Like, you think Miroku's cuter than Inu-Yasha? Oh my god, you're such a bock-uh.
Many people are learning Japanese from Anime, and they say baka so much in anime people are catching up on it and saying it to.
It's an easy way to insult someone and not get caught

The teacher doesn’t know Japanese so she/he doesn’t catch her.
