This is less cliche, but rather misuse that drives me bonkers -- using "literally" when they mean "figuritively."

"I literally died!" Yeah -- um, if so, why are you still able to talk?

I also hate hearing people talk about "poisonous snakes" when they mean venomous. A poisonous snake would harm you if you eat it. Venomous snakes, I understand, can be quite tasty.
