N. Small covering around the scrotum used to protect against splashback from wet farts. Usually a simple napkin, piece of toilet paper, or tissue. In some countries it is customary to have intricately designed, hand-woven, fart bibs that closely resemble a hacky sack, or footbag, cut open and stuffed full of man sack.

In Tanzania a fart bib is called a "Scroat Scarf," is heavily decorated with the diamonds from the past 8 generations of wedding rings belonging to the previous 8 paternal mothers. The Scroat Scarf is first presented to a young man, or Salamahawk, on his fourteenth birthday just prior to the the imbibing of the tribal hot sauce and his subsequent Chicka Mo'jumblies (the feast of three dozen hot wings upon lactating breasts which turns the youth into a man).
