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!"
