The phrase comes from Ray Parker Jr.'s 1984 Ghostbusters theme, where the chorus repeats that bustin' makes him feel good. Decades later the line was revived by Neil Cicierega's 2015 mashup 'Bustin', which looped and stretched the hook until it became a standalone meme on Vine and YouTube. The newer spelling 'bussin', slang for something excellent, especially food, gave the clip a second life on TikTok and soundboards, where the short sung hook is now used as a quick feel-good stamp.
