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.

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.

One who has had his/her head up his/her (or someone else's) arse for so long that they have adapted to the methane rich atmosphere. See Also: Craniorectal Inversion
The Sales Department is populated entirely by methane breathers. Even if they could pull their heads out of their asses, they would probably die of oxygen overdose. See Also: Cranio-rectal Inversion

People who live in N.H. or M.E. mostly lumber-jackers, or hill-billies. Mountain beathers can't afford good dental services, and have to drive three hours on dirt roads to get to their destination. Nobody comes to visit them, because nobody can find them, way up high in the mountians. Mountain breathers, are enviormental and ride tractors and go hunting for their food.
Ex: a mountain breather is someone with overalls and suspenders. Someone who doesn't know a thing about political statuses.
