showrexia 

A case among actors in plays that, when a show is about to open, they simply stop eating, sometimes due to nervousness, sometimes due to vanity. In extreme cases, the actor will stop sleeping, also.

Holy crap, Mandi fainted! I guess her showrexia finally caught up with her!

swolrexia 

The psychological disorder of a constant feeling that you're not swole enough.

Me: 'Damn, my arms be only 24s'
Brah: 'Shut up brah, you got swolrexia.'

Shownesia 

Realizing you have binged a show before after binge watching at least half of the 1st season.

On Saturday I started watching The Dome but on season 2 I realized I watched it before, I had a terrible case of shownesia.
