Requiescat in pace became a signature phrase in the Assassin's Creed series, spoken by Ezio Auditore da Firenze after assassinating major targets. The Latin wording means rest in peace and framed his kills as a ritual rather than simple revenge. It features prominently throughout Ezio's trilogy, including Assassin's Creed Revelations from 2011, where the line closes many story assassinations. Clips of the delivery later spread through gaming videos, memes, and soundboards, where the short phrase is now used as a respectful but theatrical sign off for any defeat or departure online.
