Sneaky fart 

A fart that sneaks up and surprises you and you know you farted but the smell is unrecognizable to you.

"wow! that was one sneaky fart... i don't remember eating raw sewage."

Sneaky Fart 

A fart that results in you shitting yourself. It feels like it is going to be a normal fart but when you go to release the fart it is not just gaseous but also comes with out with liquid feces. The liquid feces is the sneaky part because it uses the fart as means to make you shit yourself.

I had a sneaky fart today when I was waiting for the bus so i had to run home to change my underwear.

Sneaky Fart Suit 

When snowboarding in the intense cold or active snowfall, it is advisable to create a seal preventing the entry of such discomforts.

in the event this transpires, you may fart. the fart will encase your body and eventually move towards the only opening, your face. you will receive notice that your sneaky fart suit is zipped up once you can smell it. this may surprise you.

active pressure to the fart suit my lead others to believe that you have a fart mask on, see fart mask.

guy 1: whats wrong man?

guy 2: ugh, yuck.

guy 1: ah dude, you putting on a sneaky fart suit?

guy 2: yea, i just zipped it up, its covering my face now.
