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.
