Potty Wee Potter
From UnknowableWiki
Potty Wee Potter is a nickname Peeves mockingly uses to refer to Harry Potter, right before the poltergeist sees Nearly Headless Nick and Ernie Macmillan petrified. Peeves then starts screaming, and, in the middle of the chaos that follows, attributes the attack to Harry's doing (CS11).
Peeves also uses this nickname to mock Harry in 1995, when Harry is kicked out of Umbridge's first Defence Against the Dark Arts lesson and meets the poltergeist in the hallway (OP12).
