mumbletank 

This is the place in which a person will find themself after they have consumed so much alcohol, chronic or other mind-altering substances that anything and everything that comes out of their mouth will be completely and utterly unintelligible.

That cretin just chugged 2 pints of MD/20-20 and he will be deep in the "mumbletank" for the foreseeable future.

mumbletard 

Despite being incapable of stringing two cogent thoughts together, this low-intellect goober will drone on endlessly, boring everyone with their sophomoric points of view. Their speech is often unintelligible and paced like a metronome. They are completely unaware that their audience just wants them to shut the fuck up.

What's up with Barry? He's driving everybody crazy.

He hasn't been the same after he lost his job at KFC.

Now he's just a mumbletard who can't shut up with no job and no friends.

Mumbletoning 

Word: mumbletoning
(verb)
Definition: The act of mumbling along to the melody of a song when you don’t know—or can’t remember—the lyrics, but still want to join in.
Example:
"She was totally mumbletoning her way through that 90s ballad, and it was glorious."

Origin:
The word mumbletoning was coined in 1999 by Gemsgems during a hilariously hazy drive to her Saturday job at Miss Selfridge. Hungover and half-functioning, she found herself making vague, tuneful noises to a song by The Corrs. When her college mate asked what on earth she was doing, she blurted out, "I’m mumbletoning!"—and just like that, a word was born. It’s been part of her vocabulary (and her hangovers) ever since.

#mumbletoning = mumbling to the tone of a song when you don’t know the lyrics 🎶
