Female version: A gorgeous outgoing gal who likes to kick life in the face. This chick is such a bad mutha "SHUT YO MOUTH!" that every guy faints when she walks by. In a way she's like Medusa, one look at her big pretty eyes and you're sure to turn stiff as a rock.

Male version: creeper...
"Daammmnnnnn man, what does that chick rate? 9? 10?"

"Nah bro, she's a Sisk"

male version: a thirty year old virgin. who likes to wack it here and there (watch out for that BIIIIIIIIIIIIIIIIIIIIIIG FELLA!!)

"I just fucked a sisk! He was 12 inches when folded in half!"
