I think the most common use would be the Internet slang used for asking Age, Sex and Location A. Hi, asl? B. 32/male/California I wouldn't use it with just anyone, though

And right after this question they usually ask: "Do you have a cam?" And invite you to the hell.

I agree with Mine, this can be used by Scammers/ spammers.
