Get the rennie mug.
A term used by Renaissance festival performers and artisans to refer to the faire patrons who try to look/act authentic, but fail horribly.

They often wear clothing they made themselves -- which shows admirable effort -- but they often make terrible mistakes such as wearing a hoop skirt without a real skirt on top or a bodice with no boning. Men will sometimes try to pass a lady's pleated skirt off as a kilt.

Some wear clothing found in a costume shop and look as if a Disney movie or Tolkien novel threw up on them.

The worst of them use the renfaire as an excuse to dress unacceptably slutty. A buxom woman might wear an open-weave crocheted brassier. A man might wear pants slit all the way up the side (which would acceptable and historically accurate with another pair of pants underneath).

Worst of all, they will get disgustingly drunk and try to hit on everyone they see, creeping out performers and patrons alike.

Rennies are the ones who give Renaissance festivals bad reputations.

Used with disdain.
Ugh, that rennie is wearing nothing but a chain-maille loincloth.

Any individual to whom the following axioms apply:

1.) Not height/weight proportional (see fatty)
2.) Unable (or unwilling) to bathe themselves on a regular basis
3.) Live eight months out of the year in a pathetic, perverse, slug-like, and anti-social haze that involves playing copious amounts of fantasy role-playing games, whining about the lack of a current renaissance festival, and casting spells on those who do possess some semblance of social normality.
4.) Works for an ISP.
VanCleve shot down the rennie in dial-up that invited him to her pagan love circle at the Renaissance Festival.

1)The act of being, or appearing totally awesome. Someone who is described as being a 'Renny' will always be super beautiful, super sweet, and super talented. This word is commonly used to describe a girl who is either highly musically talented or an amazing dancer. 'Renny's' can oftern be spotted in their natural habitat-anywhere awesome.

2)This word is derived from the english word 'Renny' that is the name of a girl whose best friend loves her and worships her coolness. Renny is quite famous for being beautiful and caring.
Person 1: OMG I wish Louis would fall in love with me!
Person 2: No chance, you'd have to be a Renny.

Hot guy 1: Wow...she's beautiful!
Even more hotter guy: That must be Renny, I've heard about her.

A beautiful and stunning girl who turns heads on the streets, and causes instant boners. This is the type of girl you see in your dreams and when you wake up you wanna kick yourself because its not real. Usually someone short, curvy, brunette. All the guys want her.
