A handlebar moustache is a growth of hair from the upper lip of a man, including only hair from within the upper lip and within the smile lines, and not including hair growing from
skin below the corners of the mouth. Such a moustache
will have hair at either side that is allowed to grow longer and extend out to the sides, or upward or downward, and which
may be
straight - more or less - or naturally curled, or curled with the aid of
heat or grooming
aids such as waxes, pomades or glues.
A handlebar moustache is considered a highly distinctive style for a man, adding a sort of exclamation point to his personal style. Some feel such is odd or strange, but it's merely rare these days, and those who wear them like the individuality or
nostalgia of the style.
An important note is what is NOT a handlebar moustache: many people believe that a horseshoe goatee or "biker mustache" (like Hulk Hogan is known for) is a handlebar moustache. Such consists of a mustache on the upper lip connected to a growth of hair in a column from the corners of the mouth
straight down to the jawline. A moustache doesn't include cheek, jaw or chin hair, thus this is not a handlebar moustache. It is a goatee with a moustache.
