Found some more... I'm beginning to feel like a BF anthropologist. Dig another layer down and discover a whole new civilization.

tire suck: someone riding your @ss to draft (sorry super mod, don't hurt me)

pulling: intentionally allowing someone to tire suck you

pcad: somewhat of a local legend from what I can tell. Best guess is that this is a BF member patentcad who has over 47,000 posts

century: a 100 mile ride

Anybody know what MUP is? In context, "I was riding the MUP the other day..." multi-use path maybe?
