When
two gals with bootys competing in some way.
Could be shakin' booty to some
music.
Or it could be a "booty-to-booty" battle if ya know what I
mean.
The two booties have some contact like, bumpin, slamming, pressing and comparing each others booties together in a competitive way.
"A
woman two another: lets compare our booties and have some "Battle of the booties" action."
"Lets
shake our booties"
"Wanna have some booty fun together?"
"You can't
beat my booty"
"Lets compare our booties"
