fartionate
Describes the beneficial status of someone's passing gas, such as the timing, quantity/odoriferousness, decibel-volume, etc. of said whizzpopper, which gave you an unexpected break; perhaps it allowed you a "second chance", covered some other embarrassing/revealing noise, changed the subject, relieved an awkward silence, etc.
Unexpected anal-eruptions can also be decidedly "UNfartionate", as well, such as when you're in the middle of "delicately" undressing a hot chick in preparation for sex, giving someone a massage or soothing/comforting embrace, etc.
Fartion
Pronounced FAR-shun. Rationing a fart in order to use it at a more "appropriate" time.
I had bad gas while sitting at my desk so I fartioned it to use while in the elevator with my boss later.
