woman with a large flabby ass; fat chick. Derived from observation of a woman fitting above description. The word "Sweetheart" was written across the ass of her pants. Only "Swart" was visible; the rest of the word was sucked up inside her ass crack.
Did you see that swart get into her car? It tilted a foot to the left!
The devastating combination of passing gas whilst one is excessively sweaty. A prime example of a person displaying this behavior would be the ever klassy Brandon Davis, as I'm sure in all his alcohol induced obnoxiousness and sweatiness he passes some mean farts.
While I was on the treadmill today, my bean burrito kicked in something vicious and I swarted so loud the entire gym heard it!
