Top definition
A person who takes control of an elevator (lift) by pressing every button OUTSIDE the lift by running down/up the stairs.

The person watches a crowd go down/up the elevator, the person then runs down/up the stairs and presses the down/up button so that the elevator stops on that floor when no one is waiting to get on. The liftjacker keeps repeating until he/she reaches the top or bottom floor or until he gets caught where he runs out of sight for his next "act of terror".

This causes huge outbursts of anger and annoyance.
