gas mask

The girl has her head in a pillow and ass in the air. You put your mouth on her peach hole and your nose in her A-hole. Then just start sucking and snorting like mad man (or woman).

Last nicht I saw my dad do a gas mask on my aunt.

Gas-Masking

Holding in your fart around girls or a new girl you're hanging out with. Once 4 months pass by, it is acceptable to unleash the fury of your anus upon her.

Hey Matar,
Oh key Alek what's up?
I was hanging out with a new girl today, but I had the WORST farts. I was Gas-Masking the whole time.

gas mask

When a girl is laying on her back and you're facing her feet, you squat and teabag you're balls in her mouth and fart in her her face.

My girl spilled wine on the rug and while she was cleaning it up and I flipped her over and gave her the gas mask.
