Get the Mouthbreathermug. The actual meaning of Mouthbreather is someone who has a deviated septum and therefore has trouble breathing through the nose. But people misunderstand the reason that they breathe through their mouths and misintepret it as an insult and don't realize that it is not their fault.
Poor John has a deviated septum and can't breathe very well through his nose. He doesn't have enough money or insurance for the surgery, so he has to endure all the insults and is labeled a mouthbreather
