Joroach is another name for stupid Jonas Brothers-fans who can't shut up for one second while they're screaming "OMG NICK JONAS I LYK LUUUURVE U!!!!111eleven" and don't seem to realize that JB are just failing to copy Panic At The Disco, and trying to be a rock band when they're just a pre-produced Disney pop-band.
PATDonline forum-girl 1: OMJ now Joe Jonas is performing in a top-hat, guyliner and skinny jeans just like Brendon Urie!!
PATDonline forum-girl 2: Gah, I hate Jonas Brothers and I bet all the joroaches love that he's a Brendon wannabe.
