when you tea-bag a girl but instead of just dipping your balls in her mouth you put them (wet mind you) on her forehead and drag them back to her mouth then re-dip (can also be combined with the dip tickler)
man i thought becky was a prude untill she told me she would let me drag bag her
a variation of the teabag in Halo Reach. to perform a drag bag, squat over a dead opponent's chest and move forward in a crouch before he respawns, dragging your bag over his visor and forcing him to watch the maneuver. for maximum amusement, donkey punch him while dragbagging.
SlimJim just pwned Buck, so he dragbagged his corpse to add insult to injury
