Holy cow Batman, it's a drinking game about our campy antics. Grab some beer and tune in.
BatBeer is played while watching a "Batman" movie (original 60's or those Michael Keaton ones), or the TV show, (original or 90's animated). Every time anybody says "bat"-anything, you take a drink. If Robin says "holy"-anything then finish your beer. If Robin is in really being "holy," you may want to change this to 5 gulps or so. If O'Reilly says anything Irish (original shows), then you chug an entire beer.
