Scheisty 

Adjective: Pronounced (Shy-Stee)

Having to do with being shady, scandalous or otherwise devious. Appropriately used to describe someone with an ulterior motive of some kind, but can also be used to describe the action of a shady person(s).

Usually referring to something someone has done as "scheisty" (stealing from a friend, cheating on your girlfriend) goes hand in hand with saying that the person who did it is scheisty as well.

How you gon' just steal from ya man like that?
You guys have been boys since the fifth grade!

You're straight scheisty, playa.
