look up any word, like fleek:
 
1.
A person who constantly spills coffee due to carelessness. They often have coffee stains on the inside of their car, countertops, desks, books, and carpets. A coffee clutz also tends to not clean up the mess they made, due to the fact that they can't handle coffee without spilling/dropping it and they are generally lazy
Person A: Hey, what's that brown stain on your desk?

Person B: Oh, that was from the other week from when I almost ruined my laptop from spilling coffee on it, and I guess I never cleaned up my mess.

Person A: Wow, you really area coffee clutz.
