Used to describe big man boobs. This word originated from the phrase "Big Bouncers" when it got translated incorrectly. A common adverb to this would be, "jiggly", thus "jiggly mamoons".

Compliment for girls. Whenever saying it to a girl you're usually complimenting on their looks. Means they're beautiful, pretty, skinny, and just lovely in every way.
