I remember one girl saying something was "baka" in the halls last year, and she didn't even say it right (she said it in the worst American accent ever, as "bay-ka" xD). And, yeah, I notice it in chat sometimes and I do get pretty annoyed, but I won't say anything about it. I mean, it doesn't bother me that much, but if a person is doing it to look smart somehow, then it gets annoying.
