Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

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.
