look up any word, like bangarang:
Koshjhar is a way of being a prick. If people are constantly shouting "koshjhar" around you, it means you're a bit of a cunt and no one likes you. Koshjhar is a gullible twat also.
The boys shouted Koshjhar at him. He didn't know what it meant so he urban dictionary searched it
