Split Bongo

When you spread your ass cheeks apart and someone slaps you directly in the butthole

Josh: Hey Cass, I want you to give me a split bongo.

Cass: I’m gonna slap your bongo so hard you’ll burp

Bouncing Bongos

(n) large breasts with a good amount of bounce. Use with caution: a woman's breasts are not bouncing bongos unless they bounce even when she's sitting still.

Usually present on women who are tops 'cause the view is fucking awesome
Also great to hold when giving backshots

All I want in a woman is a nice pair of bouncing bongos and bunny ears
