The operating system designed by Bill Cosby and released in late 2008. This operating system is Unix based and it is distributed by CosbySoft. Bill Cosby has been a computer programmer ever since he started to eat Jell-o pudding.
CosbyOS is a great operating system, it's faster and more stable than Windows and Linux and you can play lots of cool games on it like SimTaco. The only thing that sucks about CosbyOS is that you have to make Bill Cosby Jell-o pudding every 5 minutes when you use it.

Drop The Cosbys Off At The Pool 

Anthony Padilla: Excuse me, I have to go "Drop The Cosbys Off At The Pool."
Girlfriend: What are you talking about?

drop the cosbys at the pool 

The act of pooping where the Cosbys are the turds and the pool is the toilet bowl
-Where were you?"
-Oh, I just dropped the Cosby kids off at the pool.

Cosbyism 

The religion which believes that Bill Cosby is God, and controls all things happening to mankind. At the end of a session at the Cosbyist Church of the Jello Puddin' Pop, all members eat a small cup of watermelon Jello. There is one holiday, and that is Pokey-Mans Day. On that day, Cosbyists across the world must listen to one of his comedy albums.
At the end of a prayer in Cosbyism, instead of "Amen," they say "Zip Zop Zoobity-Bob!"

drown the Cosbys 

To take a shit. Not used to literally describe any criminal act.
"Do you have any acceptible reading material for me to use whilst I drown the Cosbys?" or "Awww damnit! I clogged the toilet drowning the Cosbys again."
