What you'll find here: John Simm, James Marsters, Doctor Who, Supernatural, Richard Armitage, Torchwood, Leonard Nimoy and whatever else strikes my fancy.
Oops. James Marsters.
Using y = mx + b to measure the slope of that ass
Mathematically incorrect. Unless the ass was linear, but that’s biologically incorrect. You’d probably wanna use something like y=ax^2+bx+c because the ass is a second degree polynomial curve.
actually, unless your ass is fuckin two dimensional, you’ll probably want to use
to approximate one cheek of a dual-ellipsoid shaped ass
