A new way to describe your currency

Having lots of cool (money) allows you to do cool shit

There are many different 'types' of cool

Sensible Cool- the type of cool used to pay bills, buy food and other boring shit.

Degenerate Cool- the best type of cool ever, this is for drinking, gambling and hookers

Timely Cool- birthday cool and tax rebates

There are also a few Cool Rules,

Rule 1: Timely Cool can be converted into Degenerate Cool at any time, but not Sensible Cool.

Rule 2: You may allocate 20 percent of your monthly salary into Sensible Cool but once you have run out your fucked, even if you have 3kool sitting in you Degenerate Cool account.

Rule 3: Never accidentally call your Cool "money", "pounds", "dollars" ect and if you do, immediately apologise for your error and use the term Cool in a sentence as soon as possible in order to fully rectify your mistake.

Another dude goes into bank

Something that's relaxed not gettin stressed or heated is conisidered to be cool almost in the literal sense as cool as a cucumber. Wider definition could be acceptance, what's in the trend or fashion.
He's cool for the job

Cool is a word like no other. It describes something that is good in a way that no other word can. It will never go out of fashion because it is such a broad statement. Even though it is similar to words like awesome, good, great, etc nothing can really replace it.

Dude#1 "that's a pretty sweet ride"
Dude#2 "yep yep... pretty cool"
