Get the fucked up mug.
Someone who can't help but to fuck up whether they are natural at it or just an ass. Sometimes it's unsuspecting. It also can just be someone who fucks up by saying the wrong thing. A Fuck Up can either be a good person who is pretty damn accident prone by default or just a dipshit.
The following is A Fuck Up who says stupid things:
Donna: I love you.
Eric: I love... cake.

when something utterly wrong is happening to you and your life, usually having to do with another person.
In some bad cases the other person who caused it may not see the wrong in what is occuring.
It is also a state your life can be in.
My gf claimed she loved me and i was her best friend, then cheated on me with another guy. I took her back and we broke up and an hour later she was with the other guy and she still wanted to be my best friend. FUCKED UP!

A robber broke into my house and fell down the stairs and broke his leg. He sued me for $100,000 and won. FUCKED UP!
