Diffuser

[Sonia]

A modified down tube for a [water pipe] that instead of just having one large hole opening into the water, instead the glass comes to a closed tip, along which are several smaller holes. This supposedly [cools] [the smoke] before being inhaled by diffusing (spreading) the smoke over a larger area.

[Cami]

A person or thing that diffuses something.

[Julian]

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.

[Lanell]

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 dont see [how thats] punk, honestly. [Punks] 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.

[Kai]

Great [rock band], the [album] Making the [Grade] is an awesome album.

[Michiko]

a device that is used to make light less direct or to spread heat across an area or surface
