In short, a fart. More specially, a fart that happens when there is an impending poop and the butt wind stinks because it is going around a turd.

the nasty farts you rip when you've gotta take a dump. smells worse because the fart is passing over the turd lodged in your ass. also known as an "omen fart."
i knew we'd have to pull off at the next rest stop, because shauna had been blowing off a log for the last five miles and i had to roll down the window.
Dusting off the log.
Dusting off the log is what its called when you really have to poop, can't make it to a toilet right away, and you fart instead to help relieve the pressure.
During that meeting, I had to crap so bad that the only way I didn't was to keep dusting off the log.
farting off the log
those precious moments before your turtle head becomes a man and farts roll off of the log causing the stink to be a lot worse than normal.
"Sorry about that one guys. I'm farting off the log."

You make me so mad I'm going to tear off a log!
