As coined in the book Diary of a Wimpy Kid: Rodrick Rules, middle son Greg Heffley uses this word to call his younger brother, Manny, as an insult without getting punnished for saying a bad word. Ploopie can be used when small children are about, intead of swearing you can use ploopie to replace vulgar sayings.
At church when you drop a Bible, "Son of a Ploopie, I dropped the Bible!"
In public when your friends do something stupid "You Ploopie, you need to knock it off!"
