I may well be a minority of one, but I’ll just throw this out there: as a girl, I would be uncomfortable with my friends giving you my number without asking me. You finding out my number without even asking them (like sneaking a peek at their phone) would be even worse. I’d prefer for you to have the mutual friend give me your number, allowing me the choice to get in touch (or not). And if I were the type of girl who refuses to make the first move, I have the perfect opportunity to say to the mutual friend, “Why don’t you give him my number - tell him I’m psyched to hear from him.”
According to the Urban Dictionary, it’s someone who drives a Volkswagen. Not sure how that ties in.
This. I’m fully aware that the younger generation thinks texting is a perfectly acceptable way to communicate with anyone, but if you want to show this girl you really like her, pick up the phone.
In golf, I think they call screwing up an easy shot dubbing. So, I could see how someone who missed an almost certain connection with a girl calling himself a “dubber.”
I’m a guy, but this. Invading your friend’s privacy to get another person’s number? Cold-calling someone who didn’t explicitly give you their number? I realize that to some degree there may be an age gap here, since everyone’s number used to be published in a big yellow book distributed freely every few months, but to me cell phone numbers are private. I would be severely unnerved if someone got my number without my knowledge, and pissed at whoever let it happen.
Yeah. I’m old enough to remember when cell phones were the phone you paid for in addition to your landline, so you could take your landline off the hook (or at least turn the ringer off) when you wanted some quiet, and the three people who had your cell phone number could still get in touch with you if there was a family emergency. I remember when people changed cell plans a lot, with the goal of getting a new number, so they could start fresh, because too many people (usually, including a recent ex) had the number, and their landline was still in the phone book.
How old is the OP? I’m still getting a vibe that maybe the girl’s parents are paying for the phone (because he’s calling her a girl and not a woman? because of the general tone of the posts?) in which case, getting the number from a 3rd party is a really bad move.
Quick* off-the-cuff response to the original subject line: In addition to the mixed messages from everyone else# grow up a bit and/or adjust your approach to life. The phrase “get this girl” strikes me as one coming from a possession-oriented perspective. Humans are not owned or acquired. One wins hearts and minds only in a euphemistic manner. Understanding this will help your relationships (any relationship) become better in a zillion ways.
Good luck, honestly.
–G!
*And believe me, noob, the regular crew around here is quite thankful I’m not dumping my usual verbosity on you. On the other hand, since I’m trying to keep it brief, there’s more chance that my intended message will be misconstrued. I mean no disrespect to you with this off-the-cuff response.
#And, FWIW, I think Heart of Dorkness’ response is best – not only because it’s verbose 
but because it gives the girl the chance to either reach out to you (by calling you), hand that opportunity back to you (by having the mutual friend give you her number) or avoid discomfort if she isn’t feeling the same about you (by just not calling or providing her number).
You don’t. Ever. Sorry.
That said, while you get over it, you’ll find someone. And…
…Don’t You Dare Post About It Here!
Whip it out. Just like fishing, the best bait is a worm.
just kidding.
