Bottom Belch

a belch that comes from your bottom, otherwise known as a fart. Especially a loud one that makes your asshole seem like another mouth.

"Oh God, Kendall ate greek food for lunch and the stench from his bottom belches is overwhelming!"

Beach Ball Bottom

A large, bouncy buttox that is somewhat like a beach ball. Started with Courtney, who posesses the original beach ball bottom.
