Tagilla is one of the Scav bosses in Escape from Tarkov, the hardcore FPS developed by Battlestate Games, most associated with the Factory map and his aggressive sledgehammer charges. His brother is the Interchange boss Killa, and his loud combat barks became familiar to players long before they were clipped for soundboards. This I'm hit line was lifted from his in-fight voice set and shared online as a standalone reaction, where Tarkov fans and FPS editors reuse it whenever a heavily armoured character finally starts taking damage.
