The process of one man licking a woman's belly button (while she's in a standing position) while another man sticks his tongue into her fudge cavern in anticipation of a "jackpot!". This position can be used while the female is experiencing her monthly bloodfest.
Nick and Chad played some "slot machine" at work today on Angie. Nick was performing some oral pleasure to Angie's belly button as Chad collected the jackpot mouthful of doo-doo brownlees. Chad arose from Angie's turd tunnel with a mouthful of awards!
