I just thought that the car culture is always moving on and we should perhaps offer definitions of what modern terms mean

:-
Sick - Really cool nice (1990 - wicked; 1980 - cool; 1970 - hot

Slammed - Car that has been lowered.
Ricer - Boy racer car with tacky visual modifications.
Feel free to add your own phrases. (You never know we might launch the next automotive urban dictionary!

)
