methane manwich

When you squat over someone, inserting their face between ya ass cheeks and fart in their mouth.

Susan was snoring in her sleep so I posted up and dropped a methane manwich down her throat.

Methane Mouthwash

When you drop your drawers and bare-ass fart into your sleeping friend's open mouth as they are breathing in, causing them to jump awake and spit.

Dude, John is passed out with his mouth wide open. You should go and give him a methane mouthwash and see how fast it makes him stop snoring!
