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
