opener for extreme IOI?

i was out last night, and i remember at least 4 times walking past chicks that looked right at me and smiled real big as i walked past (i know they were looking at me because i was withing 3-4 feet of them). This is a definte IOI, but i still didnt open them because i got nervous thinking i dont have some kind of opener to use. Im always hesistant to use openers because i dont feel comfortable with them or i cant come up with one that is relevant, im not very witty. I was wondering, if i get such an extreme IOI, could i just walk up to them and say "hey you have a pretty smile, whats ur name?" The only reason why ive never done this is because its suposed to be a big no-no to ask a chick what her name is like that. I have a feeling im missing out because im not approaching these women

Why can't you make a mental note to open them later?

because it can be really hard or impossible to find them later. plus i will start second guessing myself if i wait too long.

DTM, lol Next time if a girl looks at you that hard. Here is the perfect opening and you can banter and tease with this aswell.

"Since your obviously undressing me with your eyes. I am wearing blue boxer briefs(whatever underwear you wearing)" then show them the top of it.

The reactions could be different for each girl but if you get a laugh out of it.

"Now I showed you mine...sooo"smile and point at her hips.

Thats the first thing that came to my mind when I read your post. If a girl can't have fun like this then I am not interested!

I agree with whoopie, I get this alot also... and I actually befriended a girl last night and she is going to wing for me alot
