Ploopy

Manny uses the word as an insult to Greg. When he says it, Greg doesn't know what it means. He then asks Mom what ploopy means, who says, ''What IS a ploopy?"

One day at church, Greg decided to say it to Manny, and when he does, Manny begins to cry, and the Heffleys leave early. At home, Susan bans the word in the family.
