Perhaps the ultimate slang word. It's origins are amongst African-American culture and became mainstream after Jazz broke out into popularity in the 20s and 30s. The word actually has nothing to do with the English term "cool" but is actually derived from the West African term "kule". Don't believe me? Search wikipedia.

Some dumbass motherfuckers spell it "kewl" when they chat online. What fools.

cools is the word used when young, Japanese girls refuse to refer to one person. "cools" can be a signal that the girl you are talking to wants to talk to you, but wants you to initiate conversation first. It can also be used when a conversation is dying, and is a signal that the girl in question wishes to continue said conversation. Henceforth, be very careful when proceeding.
"Hey do you see my new bike?"
"Yeah, its awesome!"
"Yeah, i got it for my birthday."

After reading these definitions for "cool" I realize many people think "cool" is something totally different than it was 30 years ago. Cool started out as unique, everlasting, and epic. Now it's thrashed around as Popular, rad, and such other mindless garb. You should talk to an older person about what cool was 30 years ago.
-Andee bought these cool pants from the thrift store, meaning noone else would be ever where it.

-I made this shirt. It's cool.

The word "cool" is a word of far superior quality than the word "awesome." The word "awesome" is connotated most frequently with bum pirates, drug-riddled shoplifters, or other people of generally poor caliber, whereas the word "cool" connotates a standard of being far exceeding all other words. "Cool" has been used throughout time and space and will continue to be the supreme king of all that is admirable, great, or majestic. "Awesome" forever will be a subset of the word "cool", but "cool" is without a doubt the indisputed champion, godfather, and ultimate, complete, freakishly perfect winner of all other words... especially "awesome."
Hey, want to jump out of a plane in a kayak and land in the middle of a class V rapids while wearing a Superman costume?" "Sure! That would be COOL!
