Usually one of two things. One, a type of fuel - handy for powering cars and whatnot. More importantly however, it's the best fashion brand ever. Diesel is special. Everything it touches is exquisite. The good people at Diesel bring us clothes that have the power to make us feel fuzzy inside. It's that feeling when you watch a Lady Gaga or 3OH!3 music video for the first time. You may not be fans, but admittedly their music videos are hard to keep your eyes off. It's like the euphoria associated with that - very exciting! Even the Diesel campaigns are cool. I mean, the whole "for successful living" mantra they've got going on. What's more, the "be stupid" philosophy is amazing. They even brought videos to places like Facebook and YouTube to elaborate on the meaning behind the philosophy. I don't mean to go on, I really don't. Although, bottom line - Diesel is cool!

Slang/metaphor to signify friendship and levels thereof.

Diesel: Friendly
Dieselness or Dieselhood: Friendliness

DIESEL SCALE:

0-33%: American Diesel- Below 50 Cetane (New Friend - Regular Friend)

33-66%: European Diesel- Above 50 Cetane (Regular Friend - Good Friend)

66-100%: Biodiesel- Cetane Unknown but helpful to the environment. (Good Friend - Best Friend)

100% & up: Fuel Cell (like those prototype Hydrogen Fuel Cells. In other words, if the Opposite Sex is Fuel Cell towards you, they like you more than a friend.)

Fuel Cell is Heterosexual only. Homosexual love is so different it requires its own fuel! See Solar Power.
(DISCLAIMER:

- Never, EVER spray Diesel Fuel on a person acting gasoline towards you!

- Even though it sounds like a quick & easy fix to a friendship, it will NOT work!

- In fact, their gasolinism will worsen, or worse- their stance towards you may sink to the abyss of being Jet Fuel!!

- This is only a slang/metaphor/analogy so please keep this in mind!)


Example 1: Hey Dane, why aren't you being Diesel tonight? Oh, DGray is possessing you again?? Dane, I know you're in there somewhere, so fight him out of your body!

Example 2: So Josh, how Diesel is your girlfriend?

Josh: She's more than that; She's pretty Fuel Cell, man!

Example 3: The most important part is- you survived. That's the most diesel thing you can ever do for us.

Example 4: That guy is acting a little TOO diesel towards you! Do you think he's showing a little... ...solarity?

Example 5: While I was on the phone at a gas station, when I saw a diesel truck pass, they increased my credit limit to $750.

However, I was at this gas station that didn't serve any diesel, so when I got done refueling, I saw a car rear-end another, which is a pretty gasoline thing to happen!

Liverpudlian slang. Often used as a nickname. Diesel sounds similar to "these will". Hence the slang translates to:
a: We call him 'Diesel'.

b: Diesel, what the fuck is that about?

a: Cos, you know, he has sticky fingers "Diesel do and diesel do". Man he'd steal his grandmothers fucking pension I tell you.
