Frakking a Cylon was the act of Frakking a Cylon or toaster. Most "Toaster Frakkers" didn't even know they were Frakking Cylons because some of the Cylons looked like Humans while other Cylons actually looked like toasters, other people did know they were Frakking toasters but just enjoyed it way to much, like Gaius Baltar and Helo.
