critical mass

A monthly gathering of people to ride bikes around a city or town. Its general purpose is to raise awareness that people ride bikes for transportation too and roads should be more accomidating for bikes. With many cyclists riding together in a group they are able to reach a "critical mass" and become a powerful entity of the roads, taking up many lanes.

Invented in San Francisco, it is celebrated in many cities across the world due to its simplicity to organize, often all you need to is spread the word about it. In San Francisco and New York participants often number in the thousands. It is usually at the end of the day on the last Friday of every month, at a standard, well-known gathering spot.

Often criticized by motorists as a nuciance, though cyclists criticise back that motorists hog the road, pollute, kill, etc.
Hey bro, want to see a movie this Friday at 5?

No man, I'm going to the Critical Mass to challenge the social norm of owning a car! Me and a few hundred other bike riders are going to be celebrating peaceful transportation. You should come. Everyone should come! No Critical mass? Start one!

critical Mass

A supposedly "deciding" Sunday service that someone of Catholic faith feels that he must attend prior to death if he still wants to avoid going to Hell.
This whole "deathbed confession and reformation" bu**s**t just sounds like another example of "critical Mass" to me --- it sounds waaaaayyyy too "easy" or "convenient" a way to be evil and selfish all your life. How can things truly be "made whole again" if you've seriously mistreated others for many years, and then suddenly atone for it "at the last minute"?? There are still all of those other people whom you've hurt (and have had their lives ruined by your meanness) to think about --- why don't you make said "born-aginner" beliefs truly count by arranging for the restorations of those other people's losses, rather than just symbolically "making your peace with God" but still ignoring all the damage you've done over the past decades?!

Critical Mass

Another far left wing terminology to support diversity. Another name for a racial quota.

"Critical mass" means that it is important for a sufficient number of "minorities" to be enrolled on campus so that they not feel "isolated." When the number of blacks dropped at UC Berkeley following the passage of 209, the opponents of 209 argued that the drop in black enrollment created a "hostile environment" for those enrolled. "Critical mass" theory also means that the remainder of the student body needs to see enough black faces so that they can benefit from "diversity."
Don't listen to that hippie fart sniffer, critical mass is just another term for a racial quota.
