CALA BOCA manke

It is Portuguese for shut your mouth, a fuller and more emphatic way of saying cala boca, which simply means shut up. In this clip the phrase is shouted and stretched out, so it reads as comic and over the top rather than genuinely hostile.

Its exact original recording is not documented, so it is best known as a soundboard meme clip. It spread through short videos, chats and edits where users drop the exaggerated Portuguese shout as a quick reaction whenever someone talks too much or says something silly.

Use it at the exact moment you want to cut someone off for comic effect, such as the start of a rant, a bad opinion or an annoying noise. Place it cleanly over the cut, keep it loud, and let the long vowels finish before the next line.
