look up any word, like the eiffel tower:
Stease (n.) A woman so "slutty" and nasty, she IS a walking disease.
The women in "Two girls and 1 cup" are steases.

"Ewww that's so steasy.."
Or if your a nasty F***; thats my stease.

Style & ease - combined.
"With that snowboard, you came down that mountain with stease!"
