The Dirty Santa is the act of a single horny male finding a sexy ass girl with a fat ass. (you cant half ass this one) literally, you go to eat her out from behind, however, first you lather up her booty with whipped cream and your choice of ice cream toppings (example: m&ms, sprinkles, chocholate chips) and you motor boat her booty cheeks while eating her out from behind, and when your done you look like a dirty santa with whipped cream all over your face, and candy all over the floor.

That one pedofile who dresses up as santa and sneaks in your chimney at 4 a.m. to give u a special suprise

A gift-giving game whereby participants are able to select a gift from the pool but run the risk of having it stolen if another participant on their subsequent selection turn decides they want it!

somewhat like a dirty sanchez. It's when a guy blows his load in his girl during anal sex then wipes his schlong on the girls face to make a white beard like santa.

The act of dipping your balls one at a time into a bottle of milk. The result making your balls look like they have a santa beard.

When you pound a girl in the ass, pull out a fudge stick and draw a beard on her while you sing "Ho, ho, ho"

Just like a Filthy Sanchez, but it's a full beard...and involves gingerbread somehow.
