The 'Martyrdom (Drop a Live Grenade When Killed)' meme is inspired by a notorious multiplayer perk from the Call of Duty series, first appearing in Modern Warfare (2007). In the game, the perk allowed players to drop a live grenade upon death, often killing the enemy who just defeated them. Online, the meme evolved into a symbol for 'post-mortem' retaliation or mutually assured destruction in social contexts. It is frequently used to depict scenarios where someone who has lost a fight, relationship, or argument performs one final act of defiance to ensure their opponent doesn't leave unscathed. Its longevity stems from the universal relatability of wanting the last word, even in total defeat.
