John Big Mouth

(Also known as "BM")
The friend you thought could keep a dreadful secret but as soon as he has an audience of at least 4 (including you) he spoils the secret and rolls it off like "It's a little joke, man, what's the big deal" when everyone is pointing and laughing at you and you genuinely want to JOACAD.

Dave: *Invites 15 friends over for a party*
John: Dave, I got something to tell you. I have a "the hub" channel.
Dave: dw your secret is safe :)
*3 hours later*
Dave: Guys, since we are watching tv, lets watch the best "hub" videos, made by our friend John!!!
John: SHUT THE FUCK UP JOHN BIG MOUTH

He told another tall tale on Ricky, what a shit mouth. Can’t he mind his own business?

Sewer Mouth

A European. It is unclear if they do not have access to tooth brushes, or if they just refuse to use them. However, for one reason or another, they manage to have the most disgusting teeth on the planet.

"A sewer mouth just joined our game - you can tell because he spelled 'Jail' as 'Gaol' "
"Why are people from Europe so annoying?"

Mouth-breather

Someone who no longer wears a mask indoors for large gatherings. These people are not anti-maskers/anti-vaxxers and used to wear their masks. Due to unclear expectations set by the CDC, state governments, businesses, and peers, they no longer wear their mask.

I was going to go to a wedding this weekend, but I'm sure there will be a lot of Mouth-breathers at the event.
