Zoeira is Brazilian Portuguese slang for joking around and messing about, and sounds labelled this way circulate widely on meme soundboards and in WhatsApp audio packs. This running effect became popular as a shorthand for frantic movement in short edited videos, where the exaggerated footsteps do the comedic work. It is still used because it is instantly understood without context, works over almost any footage, and fits the fast, absurd humor style common in Brazilian meme edits shared on social media.
