Originally spawned from distaste over the replacement of the original actor who played the lead wizard in the popular set of books by JK Rowling. Richard Harris (RIP) WAS Dumbledore, but Gambon is DumbleCunt! Now used as an insult to anyone who is a total knucklehead.
When somebody is pissing you off or is is being so stupid you cant comprehend what there saying or when you are having sex with a person and there thicc and they ride that dick like a rodeo and twirl
When you are such a sick fuck perv that you give a woman the choice of nicknames Matturbation and Harry Frotteur to choose from.
That's right the Dumblecunt admitted to enough dirty shit on a tape that I possess that he can't sue me for defamation by calling him Harry Frotteur or Matturbation. Hahahahaha what a Dumblecunt
