The female equivalent of being teabagged. It involves a woman dipping her lady parts onto an unsuspecting victim.
Common side effects for men include involuntary boners, sexual arousal and a rapturous round of high-fives from surrounding men.
In women it may lead to disgust or hopefully a random act of lesbianism.
