The process of searching a building for an empty bathroom. A successful bowl search typically relieves the frustration of uncomftorably defecating around others, although in less frequent cases the desire to urinate alone is a factor. Bowl searching can be done anywhere although it is most prevelant on college campuses.
"In college I did a lot of bowl searching."

"Sam went to the bathroom like 20 minutes ago. Jeez, what's taking so long?"

"He's probably bowl searching."

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.
