A rowdy, street-smart playboy. Has anger management issues. Shivs are normally the type of people who seem a bit phony and fake at first, but once u get to know them u wanna stay with them. Beware though. A shiv will probably ditch u the moment he finds something Better.
Remember that punk at the bar?? He was totally a shiv! The way he tried to chat us up!

you: "shiv!"
your wussy friend: "ow! my wussy ribs!"
