2.
Rennie, name meaning to be reborn. Rennies are cool people with an unusual names. Loves the beach and relaxing travel, Shopping included.
Very intellectual and insightful and can usually tell what a person's personality is just by looking or talking to a person once. Loyal to the day you are parted by death but if you play games or irritate too badly you will be cut out of Rennie's life permanently. Quiet and thoughtful to the point of making some people nervous. Really there is no scheme but I know what you are thinking.

Loves kids and would raise 5 or 6 if she could. Also loves sports. Particularly softball and golf. Loves all people named Tony and Courtney. Responds well to challenges but sometimes needs a shove to get out of the comfort zone. Can you say procrastinate? Should have been born rich as Rennies always pick the most expensive thing in the store.
Rennie is amazing and I wish I could be just like her!

4.
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.

6.
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.
