Awesome code phrase used to discretely alert friends that there is a hottie nearby. Said while looking in the direction of the hottie so friends know where to look and then agree or disagree that the subject is, in fact, hawt.
"Do cows moo?" says a girl while staring straight ahead.

Friends look in that direction and say "yeah, they moo alright" if they like what they see.

Or they say "awww no they don't" if it's a non-hottie
