A term used to describe the amount of resilience and elasticity of an object. Usually associated with
tits, but can also be used to describe a nice
ass. It is always good for a woman's
breasts to have a fair amount bounceability. Too
little is not good. Likewise too much can be bad as well. Bounceability in any other body part is most certainly frowned upon... unless you are into that kind of shit.
Bounceability can also be used as one of several standards of measurement for boobs, and is directly related cup size, perkiness, and amplitude of motion during ANY physical activity.
