When a girl has a really nice, round, and firm ass but its small
A small butt that is really firm and nice is a BUBBLE BUTT
When a girls ass is so fucking huge it looks like it's about to pop

Perfectly round, firm, skinny waist, looks good in anything.

Contrary to popular belief Bubble Butts are ~not~ big asses. Bubble Butts are round like a globe, usually complement a slender/slim body, they are very tight and firm unlike the one's on fat asses...
she is skinny but - dam - she has a bubble-li-cious bubble butt ass.
