Another name we like to use in reference to Po-Po, or Police. They drive around all slow, hide in the dark, and wait for unsuspecting prey to go by. Then they dart out after them, chase them down, and completely ruin their day by giving them a stupid ticket for something.
"Man, watch out, there's a Shark over there, parked around the corner. Slow down..."

A verb.

To shark refers to more than one person randomly walk up to an unsuspecting victim, and stare into their eyes, with a straight face. Objective: completely freak out the person, make them uncomfortable.

Also, while sharking, you cannot touch the person. Just get close.
Me and five friends sharked (name) and she almost cried.

To become so desperate and outrageously bad about something, that your action has caused you personally to "jump the shark," making you a shark. Also, to cop out.
"Mike is hanging with his girl again tonight instead of going out with us."
"Ya man, he's totally sharked it."

"Hey guys, I think I'm going to stay in tonight and watch my crash DVD instead of party with you guys."

"This party is sharked, lets go."

One who muscles in on you whilst you are trying to pick up. Sometimes involves putting you down to make themselves look good. Usually the person who just got sharked makes a shark fin action by placing there hand on top of there head like a shark fin and walks around the person doing the sharking.
