You can’t really call the word “knobhead” vulgar or foul language, it is just one of these London cockney rhyming slang that they tend to use there it appears.
You can’t even call it distasteful to some in the UK as it is part of their culture in that Cockney rhyming slang.
The term seems to have some genesis and origin in relation to a foolish person or an unwise person, maybe.
We could be right, we could be wrong.
It does appear to have a negative context to it in terms of the use of the vernacular largely.
Roy Jones Reacts To Carl Froch’s UK Slang
Boxing legend Roy Jones Jr while speaking to former super-middleweight champion Carl Froch on his booming worldwide podcast ‘Froch on Fighting’ said of it as regards one Bernard Hopkins (his old rival):
“Haha, I don’t know what a “knobhead” is, but I used to think Bernard Hopkins was up there. But he’s not. He said some real things recently, like how nobody in our prime could’ve beaten me. I respect that.”
Classic Jones and Carl Froch there.
Vintage Froch bringing his lingo to another country up front, abruptly so, hoping the guest (which thankfully in this case did) would understand him.
It worked out quite well.
Roy Jones and Bernard Hopkins are friends these days of course.
They fought twice.
Once back in the day and once later in their careers.
Roy Jones Jr won the first in 1993 and captured the IBF middleweight title from Hopkins by UD on points.
Then 17 years later in 2010 Hopkins avenged the loss by winning on UD on points himself.
