rocking out 

To enjoy music excessively, often while operating a motor vehicle. Rocking out often occurs at a stoplight and can be impulsive. Rocking out often involves playing the air guitar, air drums, and the air tambourine. The alleged rock out star usually plays every instrument in the song at least once. It rarely goes unnoticed.

There have been no reported deaths from rocking out.

Dude, I totally got caught rocking out in my car today.
So? It happens
I was listening to Ace of Base...
Ooooh snap!

boiler rooming 

A game where you get a bunch of friends, dress up in expensive business suits, and head out to a shitty bar.
Once there, you act like you are extremely wealthy and important while everybody at the bar wonders who the fuck you all are and why you're at their shitty bar.

Chuck: "Hey, call the crew, we're gonna go Boiler Rooming tonight."

Dave: "Awwww yeahhhhhh..."

Rocking Bill 

"ROCKING BILL" (Also see - "Rocking Billy Bob)

Refers to a person with limited intelligence who sits making repetitive, rocking movements for hours on end whilst both walking and sitting (possibly whilst sleeping), salivates excessively and is voluntarily incontinent of urine. May carry a large potato on his person.

General and widely acknowledged oddball.

"ROCKING BILLY BOB"

As with Rocking Bill, but clothed in a lumberjack shirt, dungaree's, a straw hat and long piece of hay / straw for chewing. Shotgun, rocking chair and yapping dog optional.

Levels of "Rocking Billy Bobness" vary, according to the number of missing or decayed teeth and the frequency and volume with which he speaks.

"Oh shit! Leg it - the local Rocking Bill is coming over"

"That fella there? He's a full on Rocking Bill"

A Rocking Billy Bob is likely to be heard yelling -

"Yeeehaaaahhh!! Ahm a gonna go find me some nigger to shoot"
