ur mom 

A funny phrase that is used as an annoying come-back. The phrase, saying it word for word, has no meaning. People usually will say it when they can't come up with a good come-back, or if they don't know the answer to your question.

Person 1: Hey, what do we have for homework?
Person 2: Ur mom.

OR,

Person 1: What does (word) mean?
Person 2: Ur mom.
