Okay kiddo, escrache is a word that comes from Argentina and it means when people go to another person's house or workplace to call attention to something bad they did or to shame them publicly.
Imagine if someone did something really bad or mean to you, like taking away your toy or bullying you. You might feel really angry and want to let other people know what happened. Escrache is kind of like that, but for grown-ups.
So, if someone did something bad or wrong, a group of people might go to their house or work and shout things at them or hold up signs with mean messages on them. The goal is to make the person feel ashamed and to let others know what they did.
Now, I know this might sound a little scary or dangerous, but it's actually a way for people to demand justice and hold others accountable for their actions. However, it's important to always stay safe and not resort to violence or threats during an escrache.
