Toasty began as a hidden easter egg in Mortal Kombat II, released in 1993, where sound designer Dan Forden would appear in the corner of the screen and shout the word after a player landed a flaming uppercut. The gag was a playful nod from the development team, and fans quickly learned to trigger it on purpose. As gameplay clips spread on YouTube and streaming platforms, the shout became shorthand for a stylish knockout, and it has since reappeared in later Mortal Kombat games, keeping it familiar to both retro players and new audiences.
