MCR 

Stands for My Chemical Romance. A kickass pop-punk and emo band that people used to mock constantly for being overly edgy and melodramatic. Nowadays, they get the much needed respect they deserve. Three Cheers For Sweet Revenge and The Black Parade are essential albums.

MCR 

Some recent band that is an "acquired taste", apparently. If you say anything bad about it, do not worship the raccoon that Gerard Way is, or in any way practice your right to free speech by expressing your dislike of this band, leagues upon leagues of preteens and lonely high school students will be on you and will either verbally assault you or abuse caps and misspell every other word to express how emotional they are about their love of this band and if you don't like them, then you're a "st00pid faggot who's never herd them so shutup st00pid prep"

Emo: XOMG IT'S MCR, HEY HEY LOOK IT'S MCR GERARD WAY'S SOOO HOT HE'S MY BOYFRIEND.
Random Person:... he looks like a raccoon. I don't care for them.
Emo: OMG HATER PREP FAGGOT YOU DONT KNOW REAL MUSIC

MCR stands for My Chemical Romance. They're a pop-rock band that plays a butchered style of emo, who are repetitive and sing about the same old crap. They play a style of music that takes no real talent whatsoever and sing songs about things that don't matter.

Hot topic emo: Hey, you wanna go listen to some emo?
Me: Sure, what bands?
Hot topic emo: MCR, Taking Back Sunday, etc
Me: That isn't emo.
Me: Rites of Spring and Fugazi are emo.
