the thumb dance is a particularly enjoyable sexual maneuver. in order to perform the thumb dance a man must be fuckin a bitch doggy style, the man will then stick his thumb in his mouth for lubrication, then firmly insert his moist thumb into the womans anus and ride that bitch like a bucking bronco.
Brady: dude, you show that bitch the thumb dance last night?
Dane: totally dude. when i was doing that bitch doggy style i was all "yo bitch, you wanna dance?" and before she could answer i had my thumb all up in that shit. she started screaming at me and shit but obviously she really liked it.
Brady: nice dude.
