I can't find this anywhere online and I don't know where to get it.
If you think you know what I am talking about please send me a link with a pic.
You know those one things that I guess its like a choker? And its like a silver color and its got like really big bead like things? I can't explain it. Well, that's what I'm looking for

Well there are a lot more descriptors that could really help us out here. Is there only one bead on the collor at a time? Can you change the beads depending on your mood/the day? Is the choker round or square? Can you tell if it's made of a rigid material (like metal or heavy plastic) is is it flexible, like ribbon or something similar? What are the beads made of? Do the beads hang down, or are they in a line around the neck? Where are you thinking this choker would sit: at the base of the neck, higher up or wherever the wearer felt comfortable? Are these common (have you seen them being worn by a lot of people?)? Even if you've never seen one before, you must have an image you are thinking of in your head :-)

Here are some examples I found on Google Images (I searched for "choker silver beads")

I just found it on hot topic's site. Its called a silver toned shot bead necklace.
Do you know what I mean? Have you ever seen females with them? Because I haven't but I want one but I don't want to be too guyish

Oh yeah! Now I know what you mean. I've seen girls wearing them for sure. Usually they're goth, though, just so you're aware. I've seen them wrap the necklaces around their wrist as a bracelet before, too. And if you add a "charm" on there (I hesitate to use that word, because a skull isn't charming, but it's a charm), it might be a little more girly. But the sample picture does have a girl wearing the necklace, no?

Where I seen it online, it was a guy wearing it.
