Another word for a flatulence.

It originally came from the informal word 'fart' which rhymes with 'mart' which somehow evolved into 'Martin'. But often abbreviated to 'martz'. And if a person, usually a boy, farts alot, they are often called 'martz the fartz' or a 'martin'.
Person 1: "Oops! I just did a martin!"

Person 2: "Eww, you are martz the fartz!"
