this is a joke, this is the definition of a joke right here folks.

This term can also be used to call someone a clown, like after someone does something stupid or irresponsible you could call them a Bernie.

Another person: Wait I didn’t know the circus was coming early!!
1st person: Oh yea silly Bernie Costello, the one man clown circus is coming back to town!!
