Vague Relationship Status(n.): The annoying tendency of a guy to obscure his relationship status on social networking sites. Instead of just spelling it out, he opts for obtuse categories and vague terminology that make it difficult to tell whether he's actually available. See: "It's Complicated" on Facebook or "Swinger" on MySpace for reference.

These guys usually go for the vague status because they're A. extremely insecure about their relationship or B. trying to pretend they don't have a girlfriend. Either way, guys who do this are bad news, and you should probably erase them from your inbox.
