BBL 

A Brazilian Butt Lift. They basically suck out fat from other parts of the body and inject the fat into the butt and hips, making the bum look big. This is dangerous because the bum has big veins and the doctors or whatever theyre called could put the fat into the fat veins going into ut big heart of gols </3
Can also mean be back later but no one says that anymore

Ur bum will never be big, just get a BBL -Me (2022, no 2023)
