The act of calling your girlfriend (or anyone for that matter) and hanging up right away simply so it says "Missed
Call from 'your name'".
Great in those many situations where you
don't want to talk to a girl, but you want her to think you cared a little
bit.
Dude A: "Crap I told that girl I would
call her!"
Dude B: "No worries, caution
call that!"
Dude A: "Thanks man, you just saved my romantic night featuring her black
silk sheets and my erotic demeanor!"
