An extremely annoying phrase used by people who have never heard of "hello." Usually people ask this when they are bored, expecting the person they're asking to entertain them.
Guy: what's up?
other guy: *sigh* stop trying to make me entertain you.

Get the what up with it mug.
1) The words that pop out of human's mouths when they desire to talk to you, but don't have the intelligence to think of something intelligent to say.
2) The words people say when they haven't taken a science class to realize that the sky is above them.
3) The words people say when they strongly desire to hear the response "nothing" or "not much".
4) The words people say when they are trying to make friends/trying to keep a friendship, but utterly failing.

Next time someone says these words to you, ask them which of the above was their purpose for saying it.
