Sans is the laid-back skeleton from Toby Fox's Undertale, released in 2015, whose battle theme Megalovania became one of gaming's most remixed tracks. Fans soon reworked that melody for brass instruments, and short trombone versions began circulating as meme audio on video platforms and soundboards. The joke works because the trombone sounds both heroic and unserious, matching Sans's deadpan humour. That contrast has kept the clip in circulation for reaction edits, gaming videos and short-form memes long after the game's release.
Über diesen Sound
The Sans trombone sound effect is a brass riff associated with the Undertale skeleton, used in memes and videos for funny, awkward or failed moments.
This short clip features a bold, slightly wobbly trombone line played in the cheeky, laid-back style linked to Sans, the grinning skeleton from Undertale. The brass is bright and cartoonish, with sliding notes and a swaggering rhythm that feels both cool and deliberately silly. It lands like a musical punchline, turning a simple reveal, entrance or fail into something instantly funny. Because the melody is instantly recognisable and the tone is playful rather than serious, listeners tend to smile before they even see the joke, making it a quick way to add personality, irony and meme energy to a scene.
