Zeeky Boogy Doog comes from Zeeky H. Bomb, a character in The Demented Cartoon Movie, where the phrase is delivered as his trademark burst of manic enthusiasm. Fans lifted the short line onto soundboards and meme pages, where its nonsense wording made it easy to reuse without needing the original plot. It spread through short edits, reaction videos and gaming clips, often as a sudden shout of excitement. Its lasting appeal is its simplicity: a recognisable voice, a repeatable chant and an energy that fits almost any over-the-top moment.
