Online, the chant is best known as the Biddy Blas clip, a name that appears in the searches people use to find it, and it has spread mainly through TikTok edits and short-form video. Its appeal is not a story or a punchline but repetition: the nonsense syllables are easy to remember, easy to imitate and easy to drop over almost any visual. That flexibility has kept it in circulation as a reaction and transition sound, especially in comedy edits where a familiar, upbeat rhythm instantly signals that something silly is about to happen.
About this sound
A rhythmic vocal chant repeating bum biddy biddy biddy bom bom, known as the Biddy Blas meme clip and used in funny TikTok edits and reaction videos.
The clip is a playful, almost musical vocal loop built entirely from nonsense syllables, with a bouncy bum biddy rhythm that rises and falls like a scat singing routine. The voice stays light and energetic throughout, bouncing between short, punchy bursts and a rolling bom bom finish that feels like a joke landing. Because the words mean nothing on their own, listeners focus on the timing and the groove, which makes it instantly catchy and a little absurd. It tends to make viewers smile, bob along, and wait for the next beat, giving short videos a silly, upbeat lift without needing any explanation.
