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!
