‘Mouth Breather’
Like yeah I don’t get this one. We all breathe through our mouths (and noses), because we have to. Yet I read this sometimes as it is used like an insult. So what are you saying? You’re insulting someone for doing what billions of other human beings have to do naturally?


You’re supposed to breathe through your nose for a few reasons but it doesn’t really matter. A mouth breather is someone who has their mouth hanging open in surprise at something mundane, it’s not that they’re breathing through the wrong orifice. They’re looking dumb.
That’s my understanding.
Also, it came from Stranger Things. Eleven says it and she’s pretty socially inept at that point.
mouth breather as an insult has been around far longer than Stranger Things
No, that insult is way older.
Not true, stranger things invented it right before they invented Metallica
I’m just happy they invented waffles and Gatorade.
I mean it was popularised by Stranger Things. People might have said it before, but its usage spiked after Stranger Things.
The insult is much older than Stranger Things
Used as insult by Uhura in first J.J. Abrams Star Trek (2009) film.
