Guest PoK: Motorcycle Culture

Today's is by Dan Lackas.

1) What is the origin of the word 'Hog'? What does it refer to now?

2) What does each of the following terms refer to:
*Squid
*RUB
*Cager
*Bluehair
*Road Gator
*Backwarmer

3)In the original Honda ad: "You could find ____ _________ _________ on a Honda"

As for answers for yesterday's PoK, I got sucked into the amazing The Vinkhuijzen collection of military uniforms on the NY Public Library's site last night. I found amazing examples of each, but they're downloaded at home, so I'll compose the answer post sometime this weekend with them. But Davey was pretty close, except on Sapper, which is my favorite.
