A: Check out their woman

Not that they want you disrespected, but actually, most guys like when you get checked out. “Having an attractive girlfriend is a status symbol, so many men like getting that external validation,” says David Buss, Ph. D., author of “The Dangerous Passion,” who researched jealous behavior. “It also boosts his perception of how desirable you are.” Of course, there are exceptions. If an insecure guy thinks you’re more attractive than he is, out of his league, he may feel threatened when other dudes look your way. And men with control issues can get agitated when another male eyes you.
