To screw over or to be fucked.

Someone who does somthing to leave others in a bad situation.

A term used to describe an unfortunate situation which is usually the result of one or more persons taking advantage of another. Under normal circumstances the person does not know that they have been 'shasted over' until it is too late.

Being 'shasted over' does not normally relate to physical violence/assault; it is more suited to describing a feeling of betrayal experienced when one realises that someone you once trusted has been deceiving you for their personal gain.
I got shasted.

They shasted me, again.

I am going to shast them all.
