When one person is pranked by another by filling his or her front yard with Christmas trees. This feat can usually only be accomplished in the two weeks following Christmas, when trees are tossed out and left on the curb for pick-up. A popular and effective method is to pack many trees against the victim's front door, so that when he or she opens said door, the trees tumble into the house, blocking the way out. Christmas treeing is not limited to front yards, it can be done in houses, rooms, cubicles, cars, or any place that a tree or more will fit.
"Did you guys end up treeing that pansy Derek's house?"
"Yeah man we Christmas Tree'd him hard bro, we hit him with 27 trees"
