OK so what's the difference between a Hoon and a Boy Racer?
The fountain of bad knowledge known as Wiki says ...
" Hoon is a derogatory term used in Australia and New Zealand to refer to a person who engages in loutish, anti-social behaviour. In particular, it is used to refer to one who drives in a manner which is anti-social by the standards of contemporary society, that is, fast, noisily or dangerously. Hoon activities can include speeding, street racing, burnouts, doughnuts or screeching brakes.[1] Those commonly identified as being involved in "hooning" or street racing are young, predominantly male drivers in the age range of 16 and 25 years.[2] "
Sounds like a Hoon is a Boy Racer to me
