asshole-pushup 

when someone eats the last bite of ice cream, takes the last hit, or simply consumes the final anything without asking anyone else first, they become an asshole. A consequential pushup or act of homage is then exhibited by the perpetrator.

"Dude thanks for not asking first before taking the last gummy worm! Get on the floor and do an asshole-pushup!"
