about 5 years ago when my little brother was in primary school he would get picked on by some kid. my brother was a really skinny guy (still kinda is) so tried to ignore it. then one day my brother went furioso (few-ree-oh-soe) on the jerk. the jerk also considered himself to be a good boxer. the jerk got beaten up, it even made it into the graduation book as everyone who saw it remembered the skinny guy beat up the strong guy, even a teacher who was watching didn't stop them cause he knew the jerk deserved it.
but the thing is my brother dosen't remember anything of the fight, thus i call it blind rage.
