devil's wind
Passing gas. Used to be somewhat polite.
Man, those egg rolls seem to have given me a case of the devil's wind.
Belgian wind devil
When you are doing the 69 pose with someone and you wrap your legs around the head of the top person, then push their head as hard as you can down. The let out a nasty fart in their face and hold them as long as you can.
Last night i had sex with this girl, and did a Belgian wind devil on her, she did not like it.
