look up any word, like cunt:
 
1.
When you're fucking a chick & you put a pillow over her face.
After a hard day at work I came home & gave my old lady a good smotherfucking.

2.
to run your bare ass crack back and fourth on a unexpecting or sleeping persons face.
The first one to go to sleep is going to get smother fucked.
