The act of sufficating your
partner with your vagina while receiving oral sex. This is usually
done while the female is stradling her partner's face while on
top of him/her.
*cough* *cough* *wheez* "Honey, can you arch up a bit more, you'll smufficate me if you keep
grinding on my face
like that!"
"Man, I was with this complete freak guy last
night, and all he kept begging me for was to smufficate him!"
