A girl who tends to meow a lot, who has very large boobs and who dances to Abba. Nikki Miller is a really great friend and knows how to make you smile.
She hates her job normally and will muff small children.

Bassist and evil genius behind Motley Crue, the band that redefined rock star excess. Nikki was a notorious drug addict who died once and was brought back, boned Iron Maiden singer Bruce Dickinson's wife, and once chased down Lars Ulrich of Metallica for yelling "Motley Crue sucks!" at him (and all this while wearing platform heels). Got clean, married two Playboy Playmates, and fathered 5 kids within wedlock and untold numbers outside wedlock. Nikki is pimp of all pimps.
Nobody, but nobody, got more first-class pussy than Nikki Sixx. Lita Ford, Brandi Brandt, Donna D'Errico, Vanity, and even the only female member Motley Crue ever had, Samantha Maloney. Ballin'.

That babe from 'Heroes', whose alter ego is Jessica Sanders, her long-lost dead sister, whose death may have involved their father.
"Did you see Nikki Sanders on 'Heroes' last night?"
"Yeah. She ripped some guy in half."
"Awesomeee..."
