Slut testing is the act of a male envisioning a newly encountered female in a hardcore porn of his choosing, in his mind. If the outcome of the experience is "Yeah she'd totally do that", then you have a slut. If not, you can bring her home to mom.
I saw this librarian today who I thought could be a total slut, but wasn't sure. So I gave her the slut test and I can just tell she's a total slut.
