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.

Katie: "I was sitting in class, and I looked over at Fred, who was staring dead eyed at the board with his mouth hanging open, like an idiot"

Rachel: "Ew, what a Mouth Breather"

Open Mouth Breather 

Open Mouth Breather - An individual that breathes through their mouth when not exerted. The individual appears to be, and ususally is, perpetually confused, not very bright, an idiot.

You see someone from Wisconsin driving along. As you pass them you see their profile and their mouth is wide open, an Open Mouth Breather. Although they are looking straight ahead, they don't see traffic stopping and slam their brakes on at the last moment. This is an example of an OMB (Open Mouth Breather)

Bathroom Breather 

The action of still being so intoxicated from the previous night of debauchery that when awoken on a workday you somehow drag your horrifically miserable self in to work and take periodic naps in the seated position in the employee bathroom of your workplace throughout the day, along with the foresite to wake yourself through the alarm function on your cell phone in a timely manner.

When referring to bathroom breathers, silent and vibrate mode are not your friends, they are both obvious pitfalls that should be avoided if at all possible. 20 minutes is the absolute maximum time you are encouraged to set your phone alarm for, as to avoid detection.

If your situation allows you to push this time limit even further, then by all means grab those extra minutes, but it is not recommended and should be considered objectively on a case by case basis.

If you exceed 20 minutes or even indulge too abundantly in this secretive tactic then you will undoubtedly be found out, possibly get fired, as well as tip your hand to the bossman of your establishment, and effectively ruin this cherished practice for future employees of said business.

Bathroom breathers are most often put in to effect by college students working bull shit jobs between classes or over the summer, as well as telemarketers and pharmacy technicians.

Garrett: "Yo TJ I need a bathroom breather man... I was out til 5 am last night beer bonging tequila and assaulting that random bar sluts vagina"

TJ: Word man, you've only taken 4 today, I think you'll be fine taking a fifth. If bossman comes lookin for you for something that matters I'll pretend like I gotta piss really bad and violently fake trip into your stall to alert you, no worries bro.

Garrett: Thanks man, I owe you next week."

Lawn breather 

A lawn breather is a firefighter that is breathing through his/or her SCBA (air pack) at unnecessary times, usually in the truck, or standing outside of the fire well away from the smoke and danger. Lawn breathers are normally frowned upon due to the fact, that when they actually have to go into a burning building, they only have 10 minutes of air left, and are the reason the entire hose/interior attack team has to be swapped out after only 5 minutes. Lawn breathers usually have fire department stickers all over their personal vehicles and multiple fire department t-shirts and hats.

Somebody go take the lawnmower and camping equipment away from the lawn breather

It's when one person talks so much that they don't leave time for somebody else. In turn this causes the assumption that they must take there breathing breaks through their ass.

Brit is such an ass breather, I can never get a word in.
