The language

[Merna]

n.

 1. A system of communication stemming from immature, and retarded humor. Over a period of time, close friends or kin develop a language through which they can speak without revealing their conversation, similar to that of [jibberish], though the words are usually pronounced by means of [mumbling], almost impossible to understand pronunciation, usually made more difficult to [decipher] by mixing in slang. Not to be confused with ebonics, ever.
