acronym for "slut with a beer gut." Not a fat girl, but one of those gals who parties like a frat guy. Often seen in denim hiphuggers. Will do shots and beer bongs with the rest of the fraternity and usually ends up in someone's bed or closet or car after consuming copious amounts of alcohol. All of the drinking as gone straight to the belly. thus SWABG.

rymes with cabbage.
