zamcot
A person who talks alot of crap at times. Most importantly, he/she could be one of the best instigators in your circle of friends. They would do just anything to satisfy their own humour or make you the main laughing stalk just so that others would laugh at. They either easily makes a person laugh or worse, they'll piss you off big time!
Stop being a Zamcot. You are really pissing me off !
