Mouth queef 

The act of air leaving your mouth with a audible noise

After chugging a liter of cola I felt the urge to mouth queef.

Queef Mouth 

Insult used to shut someone up when they are being stupid.

Another way to say "douche bag"

Jim wouldn't stop talking about planking yesterday. He is such a queef mouth.
