Definition

A driving move in which you nudge the slowpoke hogging the fast lane until they spin out and clear your path, borrowed from police pursuit tactics. It's highly effective, legally questionable, and emphatically not a technique to try at home, on the highway, or with anyone's insurance company.

Example Usage

The guy in front of me was doing 40 in the fast lane, so I had no choice but to cop bump him out of the way.
