cummouth 

cummouth is what certain people have when they try talking shit about one person

but then they go and suck on their dick (kiss their ass) behind your back .
they don't have to be physically sucking their dick to be accused of it
just metaphorically.
(all though that would be funny)

(it can also be a thing you can say randomly to your non gay friends)
(just to scare them tbh)

"ha yeah, brad sucks. hes such a asshole"

"bitch stfu, i know you got cummouth"

cum mouth bass 

When you splooge in a loud, obnoxious woman's mouth that also smells like a fresh caught bass.

Hey Stewart, remember that loud drunk bitch at the party last night?
Well, I went fishing with that ho and I caught the largest cum mouth bass ever.

Cum Mouth

When you are dehydrated and as a result sometimes form a crusty white pastey substance around your mouth.

Ryan went for a jog today, and when he came back he had Cum Mouth. I didn't tell him to save him the embarrassment.
