lepton n. (Brit.)(slang) pl. leptons
A mythical measure of velocity used primarily to describe how fast you were travelling in a car. Typically one lepton may or may not equal 10mph or 100mph or 2.734295mph.
Used so that people can post in the public domain how fast they were going, but due to the use of the mythical unit, proof of speed for prosecution purposes is unlikely by law enforcement.
The other day I managed to drag off a Porsche, he stayed with up until about 15 leptons I began to leave him behind.
