this commercial for Lasik is from "laydar vision".
Isn't "laydar" the straight version of "gaydar"?
"Laydar" is the ability to sense out a person who just wants to fuck something, anything that moves. A handy skill to have at crowded parties and bars.
PS: A related story: One I was at a Target store in Malden, MA with my friends Josh and Alli. In addition the the checkout clerk, there was a bagger, and apparently I said to the bagger, "thank you, sir," without really thinking about it. They both broke into nearly teary laughter upon exiting the store. "What?" I asked, oblivious. "You just called that bagger 'sir.' That was a woman, Joe." "Really?!" Josh paused. "I knew you didn't have gaydar, Joe, but I didn't know you also lack
gen-dar."
I'm using this scene in my book.
