What About Sinplay or Tangentplay?

As you're strolling around the convention hall, a bunch of people start taking your picture. You aren't sure what's going on, but it eventually becomes clear that they think you're some kind of cosplayer. They don't get your costume, but it's so crazy, it must be from something really obscure! The guy running the booth you're standing in front of gives you some swag in return for blocking someone else's displays.
