Bizarre... How about "So you can run an tell that, homeboy!"

For misuse, I think "I could care less" takes the cake.

It bugs me when people say something by mistake and then say "Oh just kidding, I meant ...." or "Wait, I lied. I meant ...."

I had an ex who used to say "I really kinda want....." and that bothered me, as it is an inherent contradiction.
