A4 

The opposite of a G6. As opposed to having extensive amounts of swagger, you are insanely white and square. Much like an A4 piece of paper.

'Did you see Hannah's white girl dancing?'
-'Yeah man, she's such an A4'

A4 

Audi's flagship sedan, offered in multiple power trains. The true ballers would only roll in the S4 edition in which 340hp of penis extension is bolted to your all wheel drive road gripping ride of love. Often during snow storms it is confused with a snowmobile as well.

Damn that guy must has a large penis he drives a Audi....

a4 

A fourth generation VW/Audi chassis that makes the basis for the 1999-2005 Jetta, Golf, and Beetle; also, makes the basis for the Audi TT and first generation Audi A3/S3. A4 is the chassis code for the fourth generation of the "A" type of VWAG's cars.

Usually used among VW fans to differentiate different generations of the Golf and Jetta. A4's were thought of as pretty cool to the masses, but VW fanboys who can't afford them decry them for being too heavy, even though they were faster than previous generation VW's.

This can be really confusing; the Audi A4 is built on a B5 chassis (the same as the 1998-2005 Passat).

Also referred to as a Mk4.

"I had an A3 Jetta but traded it for an A4 GTI."

"He had an A4 GTI and I was like 'how do you like that A4?' and he was like 'uh, I have a GTI, not an Audi' and I was liek OMG WTF u r lyke SUCH A RETARD you don't even know wot a A4 is???? hahahahaha I'm so l33t"
