The line comes from Resident Evil 4, Capcom's 2005 survival horror game set in rural Spain. Its main enemies, the Ganados, speak Spanish and shout threats as they attack Leon S. Kennedy, including te voy a matar. Players heard the phrase repeatedly during combat, which helped it stick in memory long after release. Clips of the shout later spread on soundboards and in gaming edits, where its recognisable delivery turned a routine enemy bark into a shorthand for sudden, over the top aggression.
