Bulloff is a darts game between 2 or more people, either for fun or to settle disagreements.

Players throw 3 darts each at the bullseye, the nearest being declared the victor. There are variations, in the case of a dead heat, there will be a sudden death bull-off to decide it, with one dart. For an extended variation of the game, play elimination bull-off, where the furthest from the bullseye is eliminated and play repeats until there is 1 left
Person 1: "My car's way better than yours" Person 2: "No way, your car's gay" Person 1: "Bull off"

Get the Bull Off mug.
"Bull" is being used as a double entendre -- meaning both the animal shown on the nickel and the other meaning of stupid or untrue talk or writing; nonsense. So, the bull is coming off the nickel and being applied to the situation at hand. The situation at hand being nonsensical.

This obscure phrase is famously used in the Twilight Zone episode "Mr. Garrity and the Graves". Rod Serling, in the intro, uses this expression in referring to Jared Garrity, who makes a living restoring life to the dead.
"Mr. Garrity, if one can believe him, is a resurrecter of the dead - which, on the face of it, certainly sounds like the bull is off the nickel." -- Rod Serling

Get the The bull is off the nickel mug.
evidently it's an older expression referring to something that is crazy or unbelievable. I heard it used on an old episode of the Twilight Zone recently, but had never heard the expression before.
such an outlandish story proved "the bull is off the nickle".
