Monkey business describes an activity where one is up to no good, but is not doing anything too harmful. Monkey business does not cause you to get arrested but will provide a good laugh. From prank phone calls to leaving rare pepes on your friend's doorstep, monkey business is a great sleepover activity for all to enjoy!

Monkey Business, business run by monkeys.

The term derives from ancient civilization (300,000 B.C.) when monkeys ruled the earth. They created a social climate that consisted of a modern day government system. The civilization was ran by a Democracy with voting and and various taxes. To combat the taxes put into place by the tyrannical government, many monkeys band together to create a trade system to raise enough money (currency consisted of various s types of bananas,) to pay the taxes put in place by the Government. The Term 'monkey business,' was a derogatory term used by the higher class of monkeys to shame the working class of monkeys who ran the economy.
