1. (Noun) Mos Eisley is a primitive city of Tatooine, so far on the outskirts of the Galactic Republic, that many laws are ineffective and useless, as their are almost no Goverment Officials or forms of Law Enforcement. Slave trade is a common business, and is ran by Organized Crime. This City is entirely fictional and is purely a senario in George Lucas's Star Wars.
2. (Adjective) A slang term that can be used to describe anything that is just voraciously bitching. Must be used with very much discretion as this is a very powerful term. Although, almost anything in itself can be Mos Eisley, it is solely up to the user to decide when appropriate. The user of this word must be qualified. Qualification is gained through asking permission of the Author/Inventor of this word, or being in the Inner-Circle of those who made brought Mos Eisley to its modern usage. The common result of those who use the term "Mos Eisley" in a situation where Mos Eisley is clearly un-called-for, is the user becomes a social-outcast, his/her's opinions are not taken seriosly anymore, and general humiliation from one's peers.
Please, If you don't understand the true meaning of Mos Eisley, as I am sure many of you do not, don't use this phrase. You obviously are not qualified to say Mos Eisley in any situation. The slang term is so closely related to Tits Magee
