Someone sends an instant message "Hi" to you, and you reply, "Hey! How are you?" -- and then... you wait around.. and nothing. Nothing for like forever. Then they go Idle, and leaves you with a big case of WTF?

Classic case of "hit and run".

Also, can be used when you are having a instant messaging conversation, and they leave you hanging unexpectedly...

The act of seducing a girl in order to smash her, and then shortly after, fleeing from the scene, leaving the girl wondering what the fuck just happened. In a hit and run, you either don't give the girl your name and number, or you give her a false name and number. It is a common scenario in one night stands, and is usually demeaning and humiliating for the woman, but gives the male something to gloat about to his friends.
John: Dude, I pulled a hit and run on Jessica last night!

Raph: Oh shit, so did I!

John: Oh shit, what a slut!

-Bob: "We won't be inviting her back."
