rock block

The notice of an engagement ring when sizing up a potential mate.

I saw this hottie the other day at Starbucks talking on her cellphone. She smiled at me and I thought to myself, "Game on!" That was until I approached the bar and saw the band on her cellhand. Total rock block!

Rock cheeks

Used to describe the act of having sex. Most commonly used in reference to hitting it from behind. Literally, having sex with butt cheeks.

Dude #1 : Hey bro, did you end up hooking up last night ?
Dude #2 : Oh yeah man. I took home a dime and I rocked those cheeks all night.

Dude #1 : Are you hanging out tonight ?
Dude #2 : No man, your sister is coming over tonight and she wants to rock cheeks.
Dude #1 : oh cool, wait, what the fuck ?

sap rock

Rock music tailor-made for radio airplay, featuring nice harmonies and uplifting lyrics about how hard life is and how you can overcome if you just believe in yourself.

"Have you heard the new Shinedown album? Those guys used to rock pretty hard, but now they're all about the sap rock."

Sample lyrics (Caution: may induce vomiting):

"We all know that life ain't fair/But there's more of us we're everywhere/We don't have to take this back against the wall/
We don't have to take this we can end it all"

("Bully" by Shinedown)
