As a college kid I can game pretty well, especially at parties and stuff. But my problem is I have no idea how to continue gaming after I get a snapchat/number. The last thing I want to do is be needy, so I'll usually wait a week or so to hit them up and by that time they seem to have lost interest. Do I have to randomly hit them up during the week, and just talk about random/general stuff until we can hang out again? I mean I feel like a random guy hitting you up the next day just seems desperate.

So I guess I'm asking how to balance talking to girls I barely know on snapchat without being seen as needy?
