An ass that has nice, round, plump cheeks. When apple bottom girls wear tight jeans, their ass cheeks bunch up in the bottom of their pants in a way that resembles the bottom of an apple.
This word was coined by porn sites. If you even know it that means you've gone searching for apple bottoms just like me. Spell it APPLE BOTTOM! with a "!" Because they are exciting.
