Do guys ask for girls numbers just to "show off" all their contacts who are girls?

know a lot of guys who have a ton of girls numbers who they never talk to. So guys, just some questions that have to do with phone numbers? 1. When you put your number in a girls phone, do you like them? 2. Or what about on fb if a guy asks you for your number is it usually to get to know you? Or have you ever asked just to see if they'd actually give it to you or to show off how many contacts you have in your phone that are girls?
