Schizophrenia is one that I hate, because the average person uses it wrong. I also hate demeaning words aimed at women - bitch, c***, etc. I'm lucky that I have a strong mom and two grandmothers who taught me to respect women. We can get in a debate over "do bitches actually exist?" and yes, they do...but I never feel comfortable with the word.
I'm not a fan of distinguished black fellow either, at least not the way it's been allegedly "changed". It's not a coincidence that most blacks who lived through the civil rights era don't use it as a "term of endearment"
Words I like...hmm. "Bananas".
