The phrase "HADABA!" was first used in Hoshcof's livestream of Super Smash Bros. Brawl, in which he was attempting to get 100% on the Sub-Space Emissary on the Very Hard difficulty. He said it while playing as Ness when he was struggling to stay alive, and was sputtering random words. It later became his mantra, and he and the chat would say "HADABA!" whenever he was struggling, but it was mostly used while he was Ness.
