Here’s mine: I was in a meeting with some coworkers once and my friend walked in late, walked to the end of the table, and said “Sorry, I just crop dusted all of you”. At first nothing happened, I didn’t smell anything, then one woman at the end of the table said “Dear God that’s terrible” and plugged her nose. Slowly but surely the fart wafted its way throughout the room, one of the nastiest farts I have ever smelled, and we had to reconvene the meeting outside because the smell was so bad.
I work in a machine shop where air guns are always within reach, so there’s a lot of shenanigans with farting and blowing it away, or hosing down a coworker with compressed air if they cut a stinker.
