A fart in which is the signal of trust between a couple. Usually happens when the male farts. The reaction of the female after the fart determines if she trusts you or not.
"I was watching t.v with my girlfriend and decided to give her a trust fart to see what she would do and...

(a) ...she just chuckled, now I know she's the one for me!"
(b)...she said 'oh my god...oh my god' and left....that bitch!"

Like a Trust Fall, but with a fart of unknown quality. Performed with eyes closed, arms crossed, and legs slightly apart.
I was starting to feel better and decided to perform a Trust Fart in the grocery store and shit my pants.

The DO NOT TRUST FART are questionable farts that is usually associated with diarrhea , questionable in the sense of whether or not the fart should be retained or not? the fart that you make sure you purdge out very slowly so you don't have to keep sending someone out to get you new clothes kinda fart. Prequal to a shart
From a friend to a friend I must say your ass gas is sounding wet I hope you don't end up getting a case of do not trust farts
