A new-age dance move performed by making a wanking motion with the hands, although done at the level of the nipples, such that it looks as if you are milking your fucking tits dry/wanking your nips.
Can be performed by both males and females.
May be used as a dice-rolling technique in the dice game of "Shit On My Dick."
I tore up the dance floor with my mammary wanking last night!
That mammary wank roll scored you a shit on my dick! Nice work!
