What is the meaning of "Climb a tree" ?

Hi there. The direct meaning of "go climb a tree" is to physically go and climb a tree. However, it also has an indirect meaning associated with it, and this would mean to dismiss or tell someone to go away in a rude or irritated manner. When phrases are used that do not literally mean what is written, these are often known as Idioms in the English language. I hope this helped answer your question, and we look forward to any further questions you may have.
