To "station" someone is to extend a their buttcrack with a sharpie while they are bending over, Usually at a party. The name is derived from Station; a character in "Bill and Teds bogus journey" who had a "most triumphant ass."
Off of Bill and Ted's excellent adventure, little extremely smart alien creatures with huge asses. I always call big assed hoes station, and alot of times i just holla it out for no reason.
