A child hood nick name for julia that was started by her grandma. Julia was very hyper and active child. She bounced up and down a lot when she was excited, so her grandma called her Jules la roo; thinking she looked like a cute little kangaroo. Thus the nickname was made, for all Julia's who had similar traits.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.
