Quad terminology

On entering the wonderful world of ATV's one is often perplexed by some of the mumbo-jumbo terminology encounted, some of us even find ourselves using these terms without fully understanding them. So for all you "bar hopping", "mud packing", "lappers" please consider this your ATV demystification lesson.

So...now that you guys are armed with some really cool ATV terminology, feel free to go out to the track and impress your buddies with all this fancy lingo.
