Someone who engages in hardcore partying, including tons of alcohol, drugs, and sex.
1. "We're going to have so much fun tonight, I doubt we will even remember it. We're gonna party like rockstars!!!"
2. "Did you see those guys? They went to 6 parties last night, came in trashed, and had 1 girl in each arm. I guess they partied like rockstars."

An overused term that used to apply to members of ROCK. BANDS. These Rock Bands were notorious for creating music that reflected both timely and timeless issues that stretched across generations without any gimmicks or autotune.

The term "Rockstar" is now overused, undervalued, and thrown across the spectrum of crap music (ie: Rihanna, Miley Cyrus, Amy Lee, Rappers, etc) in attempts to lure a wider audience into thinking they're "hardcore", when in reality it annoys actual Rock music listeners to no end.

The term Rockstar is not about how often you shop at Hot Topic.
"Man, Rihanna's a Rockstar ! Just look at how many spiked studs she can fit into that outfit while pretending to play drums! And she's hanging with Slash, so she must be legit!"

"No, sheeptard, she's not."

A dumb word a bunch of preteens made up on the annoying K-Mart commercials where young children think they're style is the best in the world.

See blingitude.

Warning: Please don't let this word become part of your vocabulary unless you demand self-humiliation.
Teacher: Define the word 'rockstare'.
Normal, cool student: Rockstare?
Retarded preteen with admittedly nice hair who thinks she's all that: It's the look you get when your so fucking fabulous like me!

Simply the most delicious, addictive, and energizing substance on Earth. It's pretty much liquified crack in a can.
I haven't had a Rockstar in three days and I need a fix real bad.

Rockstar is a line of energy drinks that come in a variety of flavors and types such as:

-Rockstar Energy Drink (black can)
-Sugar Free Rockstar Energy Drink (white can)
-Rockstar Juiced (orange can)
-Rockstar Juiced Pomegranate (red can)
-Rockstar Zero Carb (blue can)
-Rockstar Juiced Guava (purple can)

There are also alcoholic versions of the brand including Rockstar 21 (only alcoholic version sold in the US), Rockstar + Vodka and Rockstar + Vodka/Pomegranate.

The star in place of the A is complete marketing also. Not only does it enhance the overall appearance of the line of drinks but it also appeals to 1337 speakers.

Its slogan is "Party like a rockstar".
Ugh, another dreary Monday. I really need a Rockstar.

Someone who wont let anything get them down. They may end up drinking a lot but they look at life as an adventure and dont let anyone or anything get them down. They rock the hardest because they've been recently hurt but never give up, never look down. You don't have to do drugs to rockstar but drinking is heavily encourged.

also, sometimes... They sleep with their jeans on.
"You're boyfriend broke up with you after two and a half years of you taking care of his unemployed butt? Rockstar it!"
