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!"
The worst word you can possibly say to anyone or anything.
Gregory: Ploopy.
Manny: WAHGRSFCKEGIOWLO5IYIVP29TUYOCQXYQERGUYYFGCRGLIWL4O8T8%*%!?WILIU@V*OWT ÙOIDB
1) A word used in Diary of a Wimpy Kid: The Last Straw (By Manny).
2) The noise when your crap hits the toilet.
1)
Manny: "Hi Ploopy!"
Greg: "WHAT DID YOU CALL ME?"
2)*Grunt* PLOOPY!
A word so deadly so foul so incomprehensible to think of how much damage it can do. This word since George Washington presidentship was locked away not to be known to the public. Until one day a man discovered and said it. Rumors have come up that this man was named “Greg Heffley” but he claims it was his brother instead.
Ploopy
When you go to use the toilet and it already has poop in it from someone else.
Andy went to go to the bathroom and to his surprise he found a ploopy.
Someone whose just an absolute jerk or someone that you don't like.
