backfart

When you lay on your back on tile and move your back up and down, making a farting noise

Hey let me backfart in your kitchen.

Backfarted

When a male human farts, and the produced gas comes up through the front, bubbling underneath the subjects testicles. The horrid smell gasses the farter, making them severely nauseous, to the point of barfing on oneself.

Oh man! I needed to fart so bad, felt it coming up and decided to let it rip, suddenly I realized, it backfarted! I almost killed myself!
