Exactly what it sounds like. An emo who has been repressed, most likely due to the breaking up of My Chemical Romance. If they here Welcome to the Black Parade, they will get emotional probably
Example 1:
That One Guy Who Delivers Bad News: "Dude, MCR broke up the other day!"
Innocent Fellow Emo:"What! I have to check on Kyle! He's probably already a repressed emo!"

Example 2:
Quote on Quote"Filthy Pranker": Hey dude, check out this song
*Plays Welcome to the Black Parade*
Totally Unsuspecting Repressed Emo; "Why?!?!? You know I'm a repressed emo dude!" *Starts getting emotional*
