Christmasfy 

the act of making an object that was previously lacking in christmas spirit into something that simply reeks of christmas joy and tidings

We had no Christmas decorations, so we had to Christmasfy the area around the presents.

arkansas christmas cookie 

Arkansas christmas cookie is when one person lays in the snow making a snow angel while another person urinates on them. The urine acts as the "sprinkles" on the "angel"

My girlfriend was so excited for the first snow of the year, she laid down in it and started making a snow angel. I used this opportunity to make her a arkansas christmas cookie!

Diarrhea Christmas Lights

Explosive pixel squirts filled with colorful bytes & chunks that a video game uses to blind us.

The dragon’s maw twas lit enough due to the incoming inferno without need of copious lasers; oh how the diarrhea Christmas lights distract me so.

War on Christmas 

a figment of the imagination of Fox News concocted solely for the purpose of stoking anger against secular progressives.

According to Fox News last year, Christians won the 'War on Christmas'.

Kelly on christmas 

Drinking enough alcohol during a family function that you begin to give awkward speeches, swear uncontrollably around children, lose your phone, etc

I thought everything went great at my cousin's graduation, but I found out the next day that I got drunk like Kelly on christmas.

Christmas II 

Includes many traditions such as consuming sloppy seconds, opening gifts two at a time, having two trees and cooking twice as much food.

Made to prove that anything can get a sequel.
Date: Debatable, but thought to be some random weekday in mid-April.

Person 1: What'ya doing?
Person 2: Just preparing for Christmas II! The celebrations are gonna be amazing!
