A expulsion of foul smelling air and semen from the vaginal canal. the cum vart gets its rank smell from a mans semen that has been marinating inside the vagina for at least 6 hours.
johnny : "this morning i woke up and started to kiss lisa's vagina and she let out the worst smelling cum vart i have ever experienced in my life. it stank so bad that i vomited right there between her legs."
