The look any guy gives you that makes you really uncomfortable. The look that you know their imagination is going wild about you. It's disgusting. They are just flat-out creepy and or horny. When you sit in public and see a man looking at you as if they are drunk or high but in reality he is just imagining THINGS.
"I was talking to him but then he started looking at me with The gaze of lust" "EW! THAT'S SO CREEPY!" "I KNOW, I never want that to happen again!"
