Every emo song can be summed up pretty simply;

"I'm whiny cause my girlfriend broke up with me cause I'm a whiny effiminate fuck! Aaaand my ovaries hurt!"

And straight edge music (basically emo music crossed with neo-nazis);

"AAAARGH! I'M A BIG DUMB BELIGERENT JACKASS WHO DOESN'T UNDERSTAND THE CONCEPT OF AN INDOOR VOICE!!! *smashes into things*"
