Occurs or shows when a woman has high arches and wears a pair of high heels (i.e. hooker heels) and the arches of her feet show. It is more common to show when she is sitting with her legs crossed or just relaxed. Can be especially appealing if the woman is already considered sexy!
Karen came by my cubicle today and I was pleasantly surprised to see her arch cleavage.

Arch Linux (or Arch) is a great Linux distribution intended to be lightweight and simple. The design approach of the development team focuses on simplicity, elegance, code correctness and minimalism.

It is binary-based, unlike source-based distros (see gentoo, which is used by l33t hax0rs who think that compiling everything for a 1% performance gain is worth their time).

It is loved among knowledgeable linux users for features such as the 'pacman' package manager and the AUR (Arch User-Community Repository) which contains PKGBUILD scripts which simplify building packages not in the main repositories from source.
Arch User: What's up, gentoo user? I just finished installing Arch Linux, it took about 20 minutes.

Gentoo User: I'm just recompiling my kernel for an estimated 1% performance increase on this AMD K6. I expect it to be done in about 2 weeks. I can't wait!

When a female arches her lower back. Usually done in a standing position, bending her knees slightly, sticking her butt out, and forming her lower back into an arch for an erotic pose to get a males attention. (i.e a cat arching its back)
Damn Jillian can really arch her back!!

The cat arched its back.

Arched Back is the hottest pose a girl can do.

Arch nemesis are friends from a long time ago that have more or less equivalent powers, but also have oposing ideologies. They are therefore always fighting with each other. Examples:
- Obi Wan and Darth Vader
- The Republican and Democratic Parties
Professor Xavier and Magneto are eachother's arch-nemesis. They play chess together and have been friends for a long time, but they completely disagree about the relationship that mutants should have with humans, so they are always fighting.
