When you cough and queef at the same time.
I had a tickle in my throat that caused me to cough and queef at the same time, so I called it a quough!

Noun (n) and Verb (v): from the Greek root, queef, a Quough is when one coughs into a sexual partner's vagina, during the act of oral sex. The re-expulsion of the cough from the vagina is called a Quough.
"I've had this pesky cough for a week and the other day when I was eating out the gf I took a Quough to the face."
