People say "Monkey see, monkey do" when someone sees another person do something and immediately does the same thing. Copying another person's actions in a mindless, automatic way.
You should know this answer already, a monkey is an animal that lives in a forest or rainforest's. it depends, swings from trees, lives within a community.
If you see a monkey in your dream I believe it means that someone cheeky will come into your life at some point. My friend saw a monkey and her boyfriend now is really cheeky! So good luck!!!
THAT...
This is short for MONKEY BUSINESS. The image is of a troop of monkeys scampering around getting into everything, causing trouble. Monkey business is fooling around and getting into trouble.
