15 footer
Any woman that looks decently hot from (at maximum) 15 feet away. Anything closer will just make you want to turn around, hurl, or shudder.

Guy 1: "Shut the fuck up"

Guy 1: "yo, check out that hot piece of real estate down the way about 15 feet."

Guy1: "holy shit, nevermind"
Guy 2: "that is disgusting."
Guy 1: "please castrate me now."
