jerkability

a rating of how sexy (or appealing to masturbate to) is,
ratings go from 1 to 10,
1 being E.T. wearing nothing but a sombrero and a strap-on,
10 being Angelina Jolie 20 years ago

Josh: Heck yes! Megan Fox was so hot!!

Adam: Dude...you're stupid, she's only like a 6 on the jerkability scale.
