The title combines 'waho', the Japanese rendering of an excited 'Wahoo!', with 'onware', meaning audio that is clipping or breaking up from being too loud. The sound is tagged to Seikin, a Japanese creator known for energetic videos, though the clip itself circulates mainly as a standalone reaction on soundboards. Its appeal comes from that deliberate distortion, similar to other blown-out meme shouts where the bad recording becomes the punchline, and it remains popular for marking moments that feel louder and happier than they should.
