When a gentleman places his scrotum over his lovers eyes and then farts. this can be done in two different directions, with the fart being directed to his partners eyes or mouth.

Get the New Jersey Gas Mask mug.
A New Jersey Gas Mask is when someone makes a cup with their hand and places it over their asshole to capture a fart. After farting, they capture the gas into their hand and then proceed to cover someone’s face with their fart cup hand!
I threw up after Jessica gave me a New Jersey Gas Mask. I was smelling her fart for 1 month and a half
