KnockOuts (1992)

"You don't want to wrestle these"

In this action-comedy, a sorority girl plays poker with a buxom band of biker chicks and ends up losing all her tuition money. To scare up some quick cash, she and her sisters decide to pose for a bikini calendar. Unfortunately, they end up exploited when sneaky photographers rig their dressing room and film them in the nude. It was a rotten trick and now the girls are really angry. They are so angry that they learn martial arts and then challenge their leather-clad hog-riding rivals to a no-holds-barred wrestling match. They then get revenge upon the photographers.
