a apple
A apple is like a tight butt that's too proud to show any sign of a hip. It's firm and full, but it ain't trying to be fancy.
Friend: 'Your butt looks like a apple. Are you trying to be cute?'
TikTok: 'My butt is a apple. I'm 100% sure.'
Boyfriend: 'You got a apple for a butt. You're perfect.'
