A bullock is never a bull. A bullock is a castrated bull, and since it lacks testicles it is no longer a bull. The term isn’t specific to any particular breed of cattle.
Although bullock now commonly refers to cattle and bollock to testicles the words are essentially the same, being regional variations until very recently. From elephant shoes’s post it seems the words are still interchanable in some regons. Not surprising really.
There was a character on several tv shows who usually went by the name “Buck Naked” (the character, not the actor). I know he was on Hill Street Blues and I think LA Law, and maybe a couple of other shows as well. He would always show up in front of the judge wearing a trench coat, and at some point would drop the trench coat, revealing nothing but a birthday suit underneath, at which time he would scream his trademark “I’m Buck Naked!!”
So, if you are wondering who Buck is, he’s an elderly African American with gray hair and a trench coat.
Finally figured out how to google it and not end up with a porno movie. “Buck Naked” is actor Lee Weaver, and he apparently played the roll on Hill Street Blues and NYPD Blue, on multiple occasions for each show.
Buck’s full anme is apparently William “Buck Naked” Tully.
