Nobody wanted to be behind one of those guys who use to close down the e-club before a hump or long run. The odors waifing off or being expelled would kill you.
There was a guy in my unit in Germany who, while running in formation, would sometimes call out “Fire-brewed Stroh’s!”. That was the signal that he’d just let loose a morning-after beer fart that’d have the capacity to kill. I do know some people who actually fell out of formation and threw up due to his emissions.
