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)

Phrase meaning a large woman or man that is out of breath after only a few steps. Not attractive in the least this person resembles "Jabba the Hut" with legs.
Get a load of that Floor Squeakin' mouth breather going into Old Country Buffett, you can't wash all the parts of that gal.
If that Floor squeakin' mouth breather had a red shirt on he would look like an ugly Kool-Aid. O yea!!!
