Roadblack 

When black people either walk slowly or stand around in high-traffic areas in large groups, blocking others from reaching their destination. Walking through a roadblack could cause verbal or physical attacks. It is best to avoid such attacks by avoiding roadblacks all together.

Tom, slow down! Don't blow through that roadblack!

WHAT DA HELL?!?!? WHAT CHO PROBLEM?!?!? (punch, slap, biff)

motorcycle roadracers 

Participants in the sport and art of motorcycle roadracing. Contrary to popular opinion, most are not wreckless and do not have a death wish, but rather tend to be methodical, analytical and reasonably cautious. Motorcycle roadracing doles out severe physical punishment to those who ride beyond their abilities, and so wreckless tendencies are weeded out in short order. Having said that, it must also be noted that all motorcycle roadracers share an insatiable and inexplicable need for speed.

Top motorcycle roadracers are among the most overlooked and underrated athletes in the world.

roadtrash

n.
1. A disparaging term used to describe a person or a group of people typified as lazy or lacking style and traveling on the freeway, usually by motorcycle.
2. Any card, or collection of cards, in a cardgame hand that is neither very high nor very low but rather middling and thus undesirable.
3. Any lousy card or resource in a cardgame or boardgame.

"Hold on, an exit is coming up here. Let me pass this roadtrash real quick and we'll stop at the gas station."

"Did you hear about Andy playing hearts the other day? He picked up his three cards and threw 'em across the table! Man, I couldn't believe the roadtrash that Alex had passed him!"
