Get a Rock on! mug for your daughter Helena.
1.Most commonly used at concerts by teenagers who think they are hardcore.

2.Can used when something good happens or when in agreement with somemone.

3.Can also be used sarcastically when someone is pissing you off or yelling at you (best used with the hand motion and a serious face.) This usually implies that you dont give a damn about them or what they are saying.
1."Oh My God! New Found Glory is sooo hard core!"
::band whining::
"I know! ROCK ON(with hand motion in the air, and maybe some jumping up and down)!"

2."dude that guy gave me a 50 dollar tip by accident"
"yeaaa! rock on!"

3."GOD! i hate you! Your such a dumb bitch!"
"ohhh? ROCK ON!"

Get the mug
Get a rock on mug for your Facebook friend Beatrix.
An overused symbol that basically denotes something is cool. Some show it by doing the hand motion: a pinky and pointer finger straight out, and the other three fingers held down.
Some freak: I found $5 on the street the other day.
Another freak: Really? Rock on! *stupid hand motion*
