Guitar Hero is a rhythm game series first released in 2005, built around playing along to rock songs on a guitar-shaped controller. Battle mode turned that idea into a one-on-one contest, where players used attacks to disrupt each other while keeping the track going. Clips from those battles spread online because the shredding and crowd noise work out of context, turning ordinary arguments, gaming clips and talent show parodies into mock rock duels. The sound stays popular as a shortcut for competitive showmanship.
