It's a...one of those things that you happen to have reckless abandon sex with (sometimes in back alleys), arse kicking of baddies happens even if she's not supposed to be doing that, and one banters with when banter is appropriate (which is always), and then there's the watching of X-Files and ST boxsets while providing MST3K style commentary.
Must have frizzy hair with a life of it's own and giant moo cow eyes. Huge brain that never shuts off. Somewhat of a danger addiction. Ninja skills optional. Can do without the crotch rockets, so hopefully there's a genetic way for the harridan to remove that.
With an occasional side of nagging and stating that my eating habits are disgusting.
