Bonnet, boot, car park, petrol head, bugger, roo, and any other word that comes out of an Aussie's mouth. Pure hilarity. I don't know how they can talk to each other without breaking up into laughter!
I'm there on the "billet" thing. Not necessarily a favorite per se~ but more noticing it used to(o much) mean "goody" "here's a billet replica ashtray to set off your project jeeest right" on HorsePower or Power Trucks ..or whatever feature length commercial I was watching at the time.
I'd say that I missed out on a few of the descriptive terms after the 70's
"The hot setup" was replace with "The hot lick" about the time I step out for a "dark ages" time in my life. Now I surely missed a few between then and "that's sick". I imagine awesome was used in there somewhere.
