Slut-ometer 

The innate sense that most males are born with that tells them who is a slut, who isn't, and how much of a slut that person is. Often expressed with beeping noises.

Dude 1: Look at that chick wearing the tube-top!
Dude 2: Slut-ometer is on!
Dude 3: beep-beep-beep...
(girl gets closer)
Dude 3: BEEPBEEPBEEP

slutometer 

A portmanteau of "slut" and "thermometer" that can be used to indicate the unofficial transition from late Winter to early Spring by the visual indicator of attention seeking women immediately going from wearing full pants to short shorts or miniskirts within the span of two days.

The slutometer has indicated that Spring is declared, because I saw nothing but women's ass cheeks hanging out at Wal-Mart today.
