Mumblish 

The official language of one who speaks in a mumbled tone, usually someone too lazy to speak clearly or loudly enough for others to understand. Conversing with someone who speaks Mumblish usually leads to anger, frustration and blinding-rage.

Mumbler: "I asdfoindk to mlkasmdfo."

Non-Mumbler #1: "What the fuck did he say? I can't understand him!"

Non-Mumbler #2: "Fucking ignore him, he's speaking Mumblish again!"

Mambis 

The mambis is a male being whom (when blessed with the God given physical capability) accidentally bites its own penis off. This usually leads to the death of the mambis because the mambis tries to put the severed penis back on, instead of seeking medical help.

the female mambis is difficult to pinpoint. they are classified as a mambis because their most recent past life was cut short do to a solo wang biting accident.

Charlie: Quit yer bitchin, ya mambis
Mambis: Oh God! Does anyone know how to reattach a severed penis?!
