Depending on whether I know the guy or not, depends on what I'll do. It pisses me off when I don't know the guy, but if I know the guy and he's kidding, I'll shout something back. ^_^
unlike the other girls (and this may make me sound bad) but it makes me feel like i'm the hottest chica on the earth...and it turns me on and want to meet them
I want to walk right up to them and ask them when exactly was the last time that worked for them. I find nothing attractive about yells or whistles, or pickup lines for that matter. Its like one huge sick joke. I would love it if a guy came up out of nowhere and say hi and introuduced himself, That would be attractive.
