"Margaret was flipping the flapjacks on the oyster good last night"

"I am going to be flipping the flapjacks on the oyster with Elinor tonight"

When you’re having sex with a partner and you RKO them mid orgasm.

Kristy was squirting everywhere so I preformed the B.C. Flapjack to intesify her orgasm!
