Dressing as Santa and having sexual intercourse on December 25th.
Hey man, I think my girlfriend wants to try Santa Fucking this year.
The act of dropping your balls on your girl in the snow during Christmas Time.
Where is Tim and Jess?
Oh, they're out back santa sacking!
Ex.
- Hey Jimmy what’s that white line on the table?
-Oh, it’s Santa’s sleigh dust.
When you or your partner inserts talcum powder into the anus so stimulate orgasm.
Happy santa always makes my anus so full.
