Zuera, coming from the noun zoeira, it's a brazilian slang. It implies being loud, laughing, joking, mocking - and specially fooling around and making fun of everything in life. The broader meaning is "having a good time", usually in a group.

Zuera is more commonly used in the expression "the zuera never ends", which, since there isn't an exact term for that work in English, can be translated as "the fun never ends". This expression has been more and morefrequently used by brazilians on the internet, becoming kind of a meme for brazilian folks.

As noted by the Brazilian war on the Facebook Page of The White Moose Cafe in Dublin Ireland, Zuera may also refer to a cluster of online posts and memes, that are nonsensical in context, contain xenophobic, sexist and homophobic remarks. The application of Zuera to everyday behaviours and interactions, appears to excuse the user from any application of intelligence or reason and promotes and facilitates reactionary, ill conceived dialogue that is often violent in nature.
