Crucial 

1. Necessary, vital.

2. An obnoxious slang word that surfaced roughly 2 years ago and will not fucking die, along with "phat," "crunk," and Snoop Dogg-esque "izzle" talk. Even more annoying in its condensed form, pronounced "croosh." Usually applied to describe situations or objects in stupid and totally illogical ways.

I really wish dumbasses hadn't bastardized the definition of the word "crucial" and used it purely to describe something that is actually necessary to the given situation.

"YO MAN, I was fucking this phat ass bitch, it was so crucial."

"That's my boy Joe, he's crucial."

"This apple juice is crucial."

"I'm a fucking idiot who uses the word crucial."

An obnoxious slang word 2 or 3 years old?

Poppycock old bean.

An old time Jamaican usage which has been common in the uk for 30 plus years, my good man.

There is even a strong version of Red Stripe beer called Crucial Brew doncha know?!

It has little to do with the Mainland USA slang like Phat that our esteemed correspondent from accross the pond has related.

I say! This dub version of the Misty In Roots classic is murrrrder, crucial, wicked, and rather spendid!
