THE CAPSLOCK OF RAGE IS A PHRASE AND CONDITION POPULARIZED BY THE FIFTH HARRY POTTER BOOK, DUE TO THE FACT THAT IN THE END OF THE BOOK, HARRY SHOUTED AND YELLED AND THREW A FAIR NUMBER OF THINGS AROUND BECAUSE HE WAS IN A RAGE AT THE FACT THAT HIS GODFATHER HAD DIED FOR NO REASON BUT DUE TO MISINFORMATION AND MISCOMMUNICATION. THIS WAS SHOWN WITH DIALOGUE IN FULL-ON CAPITAL LETTERS. CAPSLOCK OF RAGE IS NOT CONSIDERED GOOD WRITING, BUT IS POPULAR AMONG MORE IMMATURE AND/OR LESS EXPERIENCED WRITERS IN THE HARRY POTTER FANDOM TO USE WHEN HARRY IS VERY ANGRY.
