Wacho is Argentine and Uruguayan slang for a guy or kid, while atrevido means daring, cheeky or bold, so the phrase works as a light-hearted label for someone pushing their luck.

Its appeal lies in that everyday, chat-born humour, making it easy to reuse whenever a friend acts a little too confidently.
