easy peasy

Easy peasy is a slang term which is used to explain that something is very easy to do. The idiom originated from a British TV commercial in the 1970s for Lemon Squeezy detergent in which a little girl points out the dirty dishes to an adult and shows the detergent. She says Easy peasy lemon squeezy. The phrase quickly became a cliche due to how often it was used, and now simply means something is very easy to use or to do.
