n. A flatulant like expulsion of air from the Vagina. Usually, and hopefully, odorless, the beaver cough is caused by air being trapped in the Vagina by the vacuum created when penetration occurs during intercourse.
The other night when I was slam - fucking Michelle, I pulled out to nut on her face when I heard a beaver cough.
