grinchitude 

Adopting a view of disdain or scorn towards Christmas and the Christmas spirit.

It's time those liberal lefties dropped the grinchitude and got into the Christmas spirit.

grinchides 

A person who tends to be very grumpy, due to a lack of sleep, and or taking naps are the most bizarre times. Mostly happens to teenagers, and gets worse as it develops. There is no real cure, besides to actually get some sleep. Grinchides can also happen when you get very sleepy at night, and the next morning/day you are very grumpy, annoying, and sometimes toxic. Not a real disease tho it should be treated as one. Can be contagious but very rare for that to happen.
