mumblypeg

A game kids (mostly boys) used to play on the playground where they stand with their feet shoulder width apart whilst throwing a pocket knife point down between their own feet. The boy who gets closest wins. Getting the knife in your foot is an automatic win.

You remember Jim Bob Cletus Scroggins? He got all them scars on his foot by playin' mumblypeg!

mumbly joe

First used by Homer Simpson to describe Bob Dole.

Used to denote a person who mumbles when speaking.

I couldn't understand a word he was saying, because he was such a mumbly joe.

Mumbly Grumbly 

Term used to describe someone who complains, bitches and moans all the time but does it in a low 'mumbled' voice, and in low, run-on sentences so you can't understand what they are saying.
Usually, but not always, limited to grumpy old men.

That old dude looks mad, and keeps mumbling something, but I can't understand him.
Yeah that's old man Withers...he's always all Mumbly Grumbly.

Mumbly-Bumbly

An inaudible slurring style of speech which is often accredited to having drank one too many.

Paul: Last night, after Mark had one too many Coronitas, he was talking all mumbly-bumbly for the entire ride home...

John: Wow, what a lightweight...

To win on epic proportions. To be awesome, and otherwise totally and completely amazing beyond belief.

That mimblewimble over there totally just kicked my ass at life and proved to the world that the cake does indeed exist.

Mimble

A mental verison of a bimble. A mimble is usually embarked upon when nicely intoxicated. You would like to go for a bimble and interact with the world, but feeling too inebriated you instead sit a while and day dream about other worldly places.

Whilst sat in a deep sofa at a friends party I found myself on a mimble, considering the merits of quiting my job & driving round the world in a second hand camper van.
