Thwomps first appeared as spiked stone enemies in Super Mario Bros. 3 in 1988, but this specific slam comes from Super Mario 64 in 1996, where they hover, grunt and crash down to block Mario's path. The Nintendo 64 version gave the fall its deep, compressed thud that players remember from Whomp's Fortress and other levels. Clips of the sound later spread on video and meme edits alongside other short game impacts like the doge bonk, and it remains a go-to shorthand for something huge landing suddenly.
