Well, the word exists - petrolhead - Wiktionary - but I have never heard or seen it used.
Student or Learner
I used the word petrolhead the other day, but the people, to whom I was speaking did not know of that word. So I tried to come up with another word meaning the same thing, but I really just could not. So I am just curious to find out, other words that have got (almost) the same meaning as petrolhead.
I am using the word petrolhead meaning a car fanatic (IMO a condescending term).
Not a teacher.
I have seen the word "gearhead" used before. I don't know whether it is a well known term.
So can you conclude that "petrolhead" is BrE and "gearhead" is AmE respecitvely?
