I have used this quite a few times and I love their reaction.

When you're chatting up a girl and you take her phone number, or if you're on a date with someone from Tinder or what not...

If you put their phone number into the Facebook search bar, 8 out of 10 times it will link you to the girl's Facebook page.

The trick is, most girls don't seem to know this so you can get free drinks, kisses out of this by betting that you can guess her surname. You can go to the toilet and check up or something, don't make it obvious and don't do it straight after the number exchange.

Enjoy

Haha I love it. I usually Facebook search thier number and learn as much about them as I can.

Wouldn't that creep the girl out if you straight up knew things about her that
she hasn't revealed to you yet?

She is comfortable enough to give you her real number. I don't see how it could possibly ruin it. I've not had any problems with it.

Worst case, she gets freaked out but it can be solved by telling her the truth.

I wouldn't do it when talking to her during Tinder though when you've only just started talking.
