Whats the best way to find out if

A girl has a Boyfriend

err... make your move on her or stalk her for a couple of weeks. Either way you're bound to know :D

You mean after you chloroform her, right?
Well you could always check her purse for a wallet or a picture book, either is bound to have pictures of a significant other if there is one.

joking.

You could just ask a girl whom you are interested in if she has a boyfriend or as omni said, if she has a boyfriend, she'll say so. even if shes lying it doesnt matter lol, either way shes not going to date you ._.

Facebook her :P

Don't worry about that--you can be boyfriend number 2. Cause the first he don't really seem like he know what to do. And you know she kinda freaky, so she's gonna give it to you. Just remember--don't fuss, don't fight, don't argue. Because second place always got a whole lot to prove. So tell her whenever she gets in the mood--you'll be her boyfriend number 2.

:P

"Hey, do you have a boyfriend?"

More Importantly, does it matter?

...why not just ask her if she does?

Punch her, and wait for another male to retaliate on you. Then you'll know.

"Sooo hot stuff....you gotta' bf?"

You have to say "BF" not boyfriend...You'll sound like a total douche, she'll feel sorry for you, and date you.

Punch her, and wait for another male to retaliate on you. Then you'll know.
