A thin line of hair that (ideally) follows the jawline. Can also be worn with a thin moustache. Essentially a chinstrap, although the only person who would consider this type of facial hair is a douchebag; hence the clarification.
Douchebag: "Hey bro, check it out! I just got my douchestrap lined up; it matches my Affliction shirt perfectly."
