caution fart 

When you’re sitting on the toilet and think you have to shit but all you do is fart

I thought I as about to shit my pants but it turns out that it was just a caution fart.

caution-farting

The act of sitting on the toilet specifically to fart to prevent sharting in your pants.

After eating the prank laxative-laced brownies I baked, my sister spent the day caution-farting.
