Acronym for "Small Tits, Big Ass". Usually used to describe women with a lack of flesh mounds but a lot of butt. Ladies with this body type usually have any excess weight go straight to their booty and very little gets stored in the tits.
Rebecca Stuart, Naomi Russell and JLo both have that perfect STBA body type. Nice small titties with big juicy ass
