A basketball move made famous by the Toronto raptors' Andrea Bargnani that's much like a layup or a dunk. the Bargnani involves lifting the basketball above the rim and then (instead of dunking) simply dropping the ball in a quite un-satisfying manner.
DAVE: Oh ya! That guy is gonna dunk it!
oh... ok... I mean he still scored, but, it was a Bargnani.
RYAN: lets change the channel.
