Diffuser

A piece of automotive bodywork that is meant to deliver downforce by channeling air under the car, especially under the midsection and rear, so that it creates a low-pressure system under the car which sucks the vehicle to the ground. This increases traction and stability at high speeds.

These are especially prevalent on high-performance sports cars, supercars and most racing cars when putting spoilers that create similar downforce would just cause too much drag.

If you don't see a big tailwing on the back of a modern supercar, look at the tail for a diffuser.

The double-deck diffusers used by a few teams caused a scandal in Formula One over the 2009 season.

diffuser

An emo-punk band. Most of their songs revolve around being hated by everyone. They sound like Linkin Park but with a twist of emo in it. I don't see how that's punk, honestly. Punk's about rising up against the system, doing what you feel like doing and not crying about your ex-girlfriend or being pushed around by everyone.

See Simple Plan.

Oh my God The World Hates Me
Oh My God My Girlfriend Left Me
There's nothing left in the world
I hope you're happy now
*A piss poor guitar solo*

hipster dufus

Someone who acts like they're into really "geeky" stuff because they think it's ironic that someone as "cool" as them would be not just a fan of it, but really into it.

At Wonder-Con, I bumped into this hipster dufus who was bragging about his band and how much he knows about the X-Men

Diffused Downstem

A glass downstem with drilled or laser-cut holes at the bottom in order to increase bubbling to further cool the smoke. Used in a bong.

John: I got an ash-catch for my bong, and a new downstem.
Bill: Is it a diffused downstem?
John: Of course, you think I'm crazed?

Duffs

a) Breasts that have not been enhanced by plastic surgery.

b) Natural, albeit smaller breasts.

Popularized in the mid-2000s when American actress Lindsay Lohan was rumored to have undergone breast augmentation surgery. Lohan vehemently denied the charges, while her declining reputation became constant tabloid fodder.

This was in contrast to her old "rival" Hilary Duff, who still maintained a squeaky clean public image and had a visibly smaller bust line compared to Lohan. Hence the term Duffs was born.

Antonym: Lohans

Person A: "Her boobs are so small compared to that chick with the implants."

Person B: "At least they're Duffs. If she's cool with that, more power to her!"
