When two or more people around someone fart around the same time causing the stink from their farts to meet at that person and making a super cloud of stink like when the cold and warm fronts of a tornado meet.
Oh man, it stinks so bad over here. I must be caught in a fartnado.
A mocawk is similar to a mohawk, however, it is located around the cock. Hence mo"cawk". To create a mocawk, one must shave the sides of his pubes to form a line that runs from the happy trail to the base of the penis.
"Hey check this out! I shaved some of my pubes! I only got the sides so it made a mocawk."
