Sharking is a parking phenomenon where a group of people in vehicles circle a completely full parking lot in an attempt to take the first spot someone else vacates.

The end result is a line of vehicles circling around a parking lot, much like sharks in the movies.
"This parking lot is full."
"How do you know?"
"Do you see all the people sharking for spots?"
"I guess we're gonna have to park at the strip mall a block away."
