A piece of twine worn around one's wrist (usually the wrist of the hand they masturbate with) until said person looses their virginity. Anyone who knows about burdon twines must wear one if they are a virgin. They are, for the most part, a secret spread only by word-of-mouth.
Guy1: Hey, nice burdon twine, loser.
Guy2: Psshh, if you know about them, where's yours? I know you've done nothing.
Guy1: Not anymore, just ask your mom!
