Any number from a musical where;
Lyrics, notes and being on key don't matter as long as you're in the "Groove"
(Also may refer to a person you would only have sex with in the dark.)

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.
