When a female's bosom appears more like a buttocks than breasts. This usually happens on fat-ass ugly chicks who don't really have tits, just chins from the neck down.
When a woman has a pair of breasts that are not only remarkably large in size, but are well shapen, and seem to bounce well when she is in motion. When you see big ass titties, it's usually accompanied by a large boner which will last you several minutes until you beat off.
