inside fart 

When you have gas and can't let it out...usually due to the fact that you are in a public place...the fart then goes back into your stomach rather than out your anus - most often resulting in an awkward noise.

Man I was in class today and I had to fart, but there was this hot chick sitting next to me so I had to inside fart instead. Turns out it was so quiet she heard it anyway and gave me a disgusted look.

You are at the brink of passing gas, but you are in a place you can’t expel. So, you suck the fart back in and rip one inside yourself. Your stomach then creates the flatulent noise, but everyone just thinks you are hungry. This is the inside fart.

I was meeting my girlfriend’s parents for the first time and had to let one go, but instead I decided to inside fart.
