Cunt.
I despise hearing the word and typing it out. It's such a disrespectful word, I just HATE it. It's hardly ever used towards me, but even if I hear it, I have the urge to pound your head in with a hammer.

Idiot.
I use this word a lot, but yet I find it such a horrible word. Nobody is an idiot, just the way they explain things is the idiotic way.

N-word.
I hardly ever type it out, but I am a hypocrite at heart, because I occasionally say this word. And I "love" how people use that word to greet someone like, "wuts up nigga" or something corny like that. But hey, that's your way of enjoying to see someone.

Childish.
For the past few months at my school, the girls used to repeatedly say, "that's childish" or "you're childish, bro". I think by just saying that makes you even more childish. But that's just my opinion.

WTF.
Some people have the nerve to actually spell out wtf, instead of actually saying "what the fuck." In my case, I love typing it all out.
