The line comes from the Spetsnaz multiplayer announcements in Call of Duty Modern Warfare 2, released in 2009, where soldiers shout Granata before throwing a frag grenade. This version reimagines that callout in the voice of Sasuke Uchiha from Naruto, mixing a Russian military warning with Japanese anime delivery. Fans share it as a crossover meme between shooter and anime communities, often alongside other Sasuke references like the Mangekyo Sharingan, and it stays popular because the short shout is instantly recognisable and easy to drop into edits.
