Rude Buster comes from Deltarune, the role playing game created by Toby Fox and first released in 2018 as a follow up to Undertale. In battle, party member Susie, the tough axe wielding monster, learns the move and uses it against enemies with a burst of red magic. Clips of the attack spread through YouTube edits, TikTok and soundboards because the sound is short, aggressive and instantly recognisable to fans. It remains popular as a shorthand for a rude, overpowered hit that needs no explanation.
About this sound
Susie's Rude Buster attack sound effect from Deltarune, the sharp axe slash and impact hit players use for powerful gaming edits and fun memes.
Rude Buster is Susie's signature axe attack in Deltarune, and this short clip captures the charging swing and heavy magical impact. It starts with a quick rising energy sound before the blade cuts through with a sharp whoosh and a deep thudding blast. The hit feels fast, rude and satisfying, like a single move that ends an argument instantly. Because it lasts just over a second, it lands as a clean punchline rather than a long battle sequence, giving any scene an immediate sense of power, attitude and comic exaggeration.
