A backside, behind, bottom, derriere, or tush that is the epitome of the peach emoji. It is so amazing that you have to say it twice. To look at it is completely hypnotizing & has you acting out of character. You respect it so much that you would never cross any boundaries, but it will make you go for broke. 🍑🍑
It's got me doing crazy things, it's your bum bum. That's got me up here in the ceiling, it's your bum bum. I'm throwing cash like it's nothing, it's your bum bum. I wish I could go & touch it, it's your bum bum.
