look up any word, like fleek:

A truly awful band from Alberta, Canada. Their music is watered-down hard rock, overplayed (especially on the ROCK radio station near the place I live, and I'm from the United States), and, coincidentally loved by pop music fans, posers, and those with an untrained ear.

Often mislabeled as "post-grunge" or, I've heard someone label them this, and I just about flipped my lid, "grunge" even. They're not even close to being grunge, much less post-grunge.

If Nickelback is anything, they're another nu metal band that's trying to be as cool as Korn, Slipknot, or Limp Bizkit for that matter.
Nickelback fan: "OMG I love Nickelback! They're so awesome and hardcore! They're grunge, baby! Grunge!"
Smart person (sporting a Nirvana shirt): "You idiot. Go listen to the Melvins or Soundgarden or Green River if you wanna hear some real grunge."

A band that some people hate and other people "hate". But seriously, Nickelback isn't THAT bad. I would much rather listen to them than what some elitist music snobs and critics call good music. Some people might genuinely dislike their music, but many others dislike them because it's the cool thing to do and it makes them think that they're more sophisticated and intelligent because they like "better music". Why don't you roll over and let the internet and music critics stomp on the other side of your face?
"That band Nickelback isn't that good, but it's much better than what my hipster friend calls good music"

Although commonly and incorrectly thought to be a musical group (band)....Nickelback have recently been identified as one of the main culprits behind global warming, suicide, and creating sounds used by the military (codenamed songs) to force the enemy to surrender. Also spanish for vomit.
Mexican Child: Mom i feel like i'm going to Nickelback.
Mexican Mother: GOD NO!?!?!?!

Normally a homosexual act of leaving a small deposit of semen mixed with faeces left on the other males back after anal penetration. Generally similar in size & colour to a nickel.
I gave him (or my lover) a Nickelback.

A terrible band from Alberta, Canada, who did a good job in revolutionizing the already-crappy music scene that exists in this world today. Nickelback invented a new level of SHIT.
Chad Kroeger: Look at this photograph. Every time I do it makes me laugh.

DE: Look at this crappy band, I want to fling shit at them.

DS: Oh yeah! Nickelback bites the big one!

DE: Pwned!
