A skank whose skankiness goes above and beyond the call of duty. A skank who's vag is so used and abused she has to apply KY on the reg just to keep her insides from drying out. A supa skank not only wants to be fucked on the reg, but her very existence depends on it. A skank whose only rules are "no like and no love."
Guy 1: Yo Bro, Im totally fucking supa skank tonight even though you had her this morning.
Guy 2: She is totes a supa skank.
