The weird, unexplained discontinuation of an IM
conversation. In many cases,
the person who, for whatever reason stopped
talking to you, is still signed on. Often occurs in intense parts of conversations.

Instant messaging:
Jill: I just got back from dinner with my
boyfriend.
Heather: Did he propose?

Heather: Don't pull an IMunot with me!
I see that you're still online!
