Mouth Breather
A person who breathes through their mouth, thus having their mouth hang open. Their mouth can be anywhere from barely open, to gaping, and usually the more open it is, the more idiotic, and unintelligent they look. Mouth Breathers may or may not be intelligent, however, due to the fact that they don't realize their mouth is gaping, they just look like a moron, who may drool at any moment, but is deffinately sucking in as much air as possible.

Mouth breathers tend to be people who are bored, zoning out, very focused on something, someone with huge lips, or someone who isn't smart enough to realize their mouth is hanging open, catching flys. All tend to appear as the latter.

People who are sick and can't actually breathe through their noses do not count.

Rachel: "Ew, what a Mouth Breather"
