Mumbet 

Mumbet is a philosophical and social construct first theorized in the Austrian capital of Vienna at the beginning of the 20th century, by world renowned theologian Mörtz Spesh.
Mumbet is a state of mind; a completeness of the soul. Once one has unlocked and can manipulate their inner Mumbet they transcend into a Mumbeteer.
A person with no Mumbet or unaware of their Mumbet is a "Marcello".

1) IS THAT A MUMBET?!

2) Give her the Mumbet.

3) “People are having a nice time here. You can drink baileys from a glass but you can’t drink it from a shoe”

4) Have you got a license to carry that Mumbet.

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.

When you have created something so incredibly amazing that you are beyond believing it's real and true. You are dumbfounded and excited from your own creative success.

The amazing creators were in a state of mumbelievmable when they realized their creation was loved by the whole world! Everyone was in shock and awe and excited by the mumbelievmable success.

Mambet 

Originally a rare kazakh name turned into derogatory term for young people from rural areas(like Shymkent, Taraz, Arkalyk etc.). Usually charectirized with very poor russian, darker skin tone, lack of proper education, predisposition to crime, constant spitting and swearing in Kazakh and Russian. Their dress code is quite similar to Gopnik's and usually they have the same habits.

1. "Takoe nosyat tolko mambety" - Only mambets will wear such clothes.
2. "Sudya po kolichestvu mambetov etot klub - polnaya hernya" - Judging from the numbers of mambets i see here this club is a complete fucking shithole.

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.
