A really hot chick that engages in uncharacteristically promiscuous behavior. While most hot girls require a nice dinner, compliments, and respect from guys before they sleep with them, a slam-tart doesn't want this--she just wants to bang and be degraded. Although they act like slam-pigs, they are hot; therefore, they are slam-tarts.
"Yo dudes I can't believe you got with those girls! They were so hot"

"Naw man, they were just slam-tarts. They both just wanted some dick so we banged each one, then pulled a switch-a-roo. They didn't even make us wash our dicks off."
