This nice looking fellow asked me out last night but my murdar alert started beeping so I said no. And I didn't even give him my real name.
like gaydar only it's the ability to know what normal looking person is really psychotic and potentially harmful.
How is anyone supposed to know who's wacko and who isn't? We all better tune up our Weirdar and make sure the 'ping' is set to LOUD.
