The sound comes from the Shoop Da Whoop meme that spread across forums and early YouTube in the mid 2000s, inspired by the exaggerated laser attacks in Dragon Ball Z. The joke pairs a distorted face, a wide open mouth and the charging shout before a huge beam fires. It became a staple of YouTube Poop edits, image macros and remix videos, often pasted onto other characters at the moment of attack. Its simple charge and release structure keeps it useful for modern meme edits and short form clips.
About this sound
The classic shoop da whoop meme voice shouting I'm firing my laser, from Dragon Ball Z edits, used for sudden beam blasts and overpowered reaction jokes.
This is the exaggerated shoop da whoop shout built around the line I'm firing my laser, delivered in a deep, distorted voice that builds for a beat before the blast. The delivery is deliberately over the top, with the mouth wide open and the energy charging up, then releasing in one ridiculous burst. It turns a simple power up moment into pure comedy, because the voice sounds deadly serious while the situation is absurd. Viewers instantly read it as a warning that something huge, silly and unstoppable is about to hit.
