look up any word, like steppin on my dick:
 
1.
When a lover takes the liberty to defecate on their significant others chin, lips and cheeks. The mouth is typically closed which would allow for a resemblance of a black/poop brown beard. The lover than can optionally top it off by accessorizing a poo-Santa hat if the said lover has any feces left to share.

(Typically done laying down, but for an extra challenge can be done upright.)
Monica gave me a Dark Santa for Christmas last night, it was more a gift for her than it was for me.
