Originating from Montgomery County, Maryland and a few individuals of AEHS Class of
2004, it's a combination of "
Shit" and "Rawr" (Roar).
Shit + Rawr = Shar
Commonly used to emphasize anger, frustration, annoyance, and just about anything really.
Shar can also be used as a verb in different aspects. Refer to the last example for this.
Agent A: Maaaaaaaan ... my roommate is such an asshole. He cockblocked me while I was flirting with
Anna from down the hall... ShaR~!
The child exclaimed shar in response to everyone's
ignorance.
Are you shar you are going to take a shar-
ar now?
