Rock Band Head 

Much like Road Head, Rock Band Head consists of a blow job while the receiver is playing an instrument of the popular game Rock Band (i.e. drums, guitar, bass, vocals).

"Dude, I was on Expert playing 'Pinball Wizard' and she got down and gave me Rock Band Head."

Rock City 

An amazing club for alternative people in Nottingham (uk) which is really fun, whether it's under or over 18 nights.
There are usually loads of people soaking wet because of water fights.
Rock city rules!

Anya: Wanna go rock city?
Mel: Hell yeah!

Rock Tits 

Ridiculously unattractive fake boobs; breast implants looking as though ready to pop if touched.

Chris suffered a fractured penis while attempting to screw Michelle's rock tits.

Mike chipped a touch on Carrie's rock tits during foreplay.

rock your knot

Largely, stands for kicking one's ass real bad, yet specifying one's groin area ("...your knot") for particular intensification of the utterance.

For steppin' on the stage I should rock your knot (from the '8 Mile' movie)

Rock hard, rock often 

"Rock hard, rock often" was a saying invented by Josh Pierce in early 2006. In an attempt to gain popularity to the saying Josh instructed all the students at Oneighty//gb to spread it around their schools. It worked. By March of 2006 this phrase was unstoppable, it infiltrated all of High School society in greater Green Bay, and continues to spread rapidly. We could be looking at an all out epidemic.

Spread the word.

Brian the stud: "Cya later Josh"
Josh: "Rock hard, rock often man"

Ryan: "Dude, let's go golfing"
Josh: "Rock hard, rock often"

Very excited senior: "I GOT EXCEPTED INTO MIT!"
Josh: "ROCK HARD, ROCK OFTEN!"

Rock Springs 

A small inbred town in Wyoming, known to most who live there as Rock Bottom. Take my advice and never go there. It's like a black hole of nothing.

See 'Shithole'
