You would find rock baby in an urban thesarus under crack baby. Rock baby is a more street version of saying crack baby, since the original term has become mainstream.
Yo look at dat rock baby wit the big forehead and drool comin' out da corna of his mouf. His mother must have been suckin' on that pipe like it was her job.
One of the most inane chants in the history of collegiate sports. KU students will, in a very Tourette's-like fashion, break out the phrase at seemly random, inappropriate times. They tend to attach a "man" or "motherfucker," further implicating their level of douche.
"Our football team is undefeated, and who gives a shit if our strength of schedule was below Yale's, rock chalk"
"We'll forever harbor extreme resentment over the departure of Roy Williams, rock chalk"
When you take a metaltube, place it around one's shaft, and insert the erect penis into a female socket.
My penis was so hard it cut every condom I used so i had to put a metal tube around my cock so that I could fuck those pussies rock 'em cock 'em robots style.
that guy who's been kicked out of every band in town. he's talented no doubt, but he's never sober and doesn't really know what stability is. lots of booze, bitches, and hard drugs, baby. he's never really grown out of that stage that all boys go through around the age of 15 when they think they'll be famous someday cause they can shred. he lives like a rock star because he thinks he'll be one some day, but man he never will be. oh yeah, his rent is four months late but you can't seem to kick him out because he's got no job and you can't picture his pretty face on the streets. sometimes people just can't outgrow a big dream.
Among musicians, especially rock musicians, "Rock Star" is the ultimate putdown/insult. It means 'prima donna.'
Tommy Lee (to Vince Neil): "Dude, you are such a rock star!"
Vince Neil: I AM NOT A ROCK STAR!!! (as he throws down his microphone and stomps offstage in a fit of pique).
