A yoohoo is someone obsessed with a certain muppet. Her home is usually R&S on yahoo answers and she trolls uncontrollably. A Yoohoo also makes others mad by stealing aways muppets. She is also obsessed with the Disney Princesses and she despises report monkeys.
Girl: Stop pissing off the parenting section on yahoo answers. You are such a Yoohoo!
