1. To masturbate on webcam (so called because Leslie Grantham was caught in his Eastenders dressing room doing just that)

2. To generally be a sexual deviant in an unpleasant manner (we can thank both John Leslie the British TV presenter, accused of some nastiness to one Ulrika Jonsson, and the aforementioned Leslie Grantham for this usage)
