Get the Butt ivy mug.
An Ivy butt is by far the best butt ever, no doubt about that. It is thick, soft, and everyone wishes they had it in multiple ways. It is rare that someone has an Ivy butt without being named Ivy. If a girl is named Ivy she definitely has an Ivy butt.

If you are with an Ivy you are very lucky!😏
Guy1: dude do you see that girls but!?

Guy 2: yessss that is an Ivy right there bc that is an Ivy butt!

Guy1: should I go talk to her?

Guy2: naw there’s her boyfriend there (making out) he’s probably an Ethan.

An Ivy Butt is the best butt, no doubt about that. It’s thick, soft, and everyone either dreams they had it or wishes they had someone with an Ivy butt. It is rare if a girl not named Ivy has one. If you know a girl named Ivy then she definitely has an Ivy butt, she is what it was named after. So just know if you have an Ivy, your very lucky!😏
