Christmasitis 

Being unable to accomplish any schoolwork due to the excitement of Christmas around the corner. Similar to senioritis.

I can't study for midterms. I have a bad case of Christmasitis.

Christmasitis 

The physical irritation due to overstimulation caused by Christmas decorations and hearing the same Josh Groban and Michael Buble Christmas CDs over and over and over again. Usually caused by overly enthusiastic co-workers and/or spouses. Initial signs may take one to two weeks to appear after first exposure, but conditions generally increase exponentially.

Related to Christmas fatigue.

"Do you mind if I turn the radio on? They've started playing Christmas music."
"Only after we stop by the store to get some Benadryl for the Christmasitis flare up I'm about to have..."

Tom Christianitis 

When your penis and genitals are so gigantic that one is physically incapable of prefroming the act of sexual intercourse without killing the partner or horrendously maiming them. The disease is associated with causing debilitating back problems, lightheadedness, causing fainting on sight, disillusioned feelings of supremacy, shit-stabbing, and causing fear of intercourse or loss of labido in others.

I had sex with this guy with Tom Christianitis, his dick punctured my lung.

Christmasification 

The act of christmasifying a house or other form of residence usually just after the thanksgiving holiday.
The act of making everything Christmasy:)

This place is in dire need of some serious christmasification, we don't celebrate no Kwanzaa!

Christmastian

A subset of Christians who read the Bible from Genesis to the nativity, and then skip to Revelations at the end, the point being to purposefully exclude the actual teachings of Jesus Christ. The Christmastian belief system is founded primarily on ancient pagan celebrations that were adopted by early Christians. Christmastians reject peace, love and forgiveness and embrace vengeance, violence and never-ending war.

George W. Bush is a Christmastian.

Christmastize 

To decorate for a holiday in a Christmas like manner for some other holiday besides Christmas.

Jill bought some of those orange lights to decorate her bushes for Halloween - yet another annoying example of the Christmastizing of Halloween.
