Gasmask 

When you put your balls into your lovers, or your one night stands, eye sockets and navigate your asshole to their mouth. Then release a big ol' stanky bubbly fart into their mouth.

Rhonda was fast asleep after a long rough fun night of some hot sex. Leroy navigated his rear end to Rhondas mouth. Giving her the best Gasmask in world history. Then Rhonda puked all over Leroys asshole.

Gasmask 

1) To cover up the sound of a fart by replicating the sound, or a similar sound several times.

2) To make a sound that sounds like farting again at least once so that the people around you realize that it was a funny noise and not you farting.

"It totally sounded like I blew one in history today when I sat down, but I gasmasked it by rubbing my hand on the desk to make more fart noises"

Afghan Gasmask 

When a man places his balls over the eyes of an unsuspecting/suspecting individual and then farts in their mouth.

Arabian Gasmask 

The supreme act of eternal matrimony in which the man slips his cornhole into the woman's nose and lets his testicles rest in her eyes. The man then proceeds to fart while the woman's nose is in his ballon knot. This creates the illusion of the woman wearing a gas mask. In some cultures this is a sacred custom which is practised in holy marriage.

"As I slipped on his Arabian Gasmask, I knew that he was the one for me. We were one soul, and one mind."

"The particular smell in John's Arabian Gasmask solidified our relationship, and I knew I was in Love"

"Me and gary continually argue over who gets to Arabian Gasmask who, He says my anus is cleaner. But I disagree due to my chronic Screechies."
