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.

Mumberlaaa! 

When someone is afraid to say what they want, so they mumble it. The person nearest to them then shouts "Mumberlaaa" in their face.

Or when someone is saying something you don't agree with but you have no real argument and resort to shouting it in their face, claiming you cant hear what there saying.

Teacher: WHAT DO YOU THINK YOUR DOING!!
Guy: Errrm, I was just, errm nothing its, I was..
Guy sat next to him: MUMBERLAAA!!
