The term 'BLITZED' in football refers to a defensive strategy where the defense rushes the quarterback in an attempt to sack him. This strategy is also known as a 'RUSH' and is often used when the offense is trying to score quickly. The term 'BLITZED' is derived from the German word 'BLITZKRIEG, ' which means 'lightning war.' Blitzing is an aggressive tactic that can be effective in disrupting the offense's plans and forcing them to make mistakes.
