Can Anyone Explain What This Man’s Sign Means? (Picture)

This one is really WTF-worthy.  Listener Eric sent this email yesterday and we’re really scratching our heads over it.  Can you figure out what this guy’s attire means?  Is he simply trying to let everyone know that he’s not gay?  Is it America that isn’t gay?  Or is there a deeper meaning here?

Hey guys,

Saw this at the local grocery store in kennebunk Maine and was immediately as excited as Justin at a sexbot convention! Finally a reason to email after all these years…..  I can’t give any context for this but the photos should speak for themselves I guess.
