While running to take a shit, you fart a bunch of times because it is against your own will.
"Oh god, did Sampson already shit himself? It fucking smells..."
"Nah dude, he just let out a few Mel Gibson Road Warrior Farts."

Get the Mel Gibson Road Warrior Fart neck gaiter and mug.
The sound your wheels make when you cross a rumble strip at the edge of the highway.
I was so tired driving home that the road farts were the only thing that kept me alive.
