rar-full of dicks
A rar-full of dicks is a file, usually a .zip or .rar archive, deliberately named something to entice people into downloading it, but is usually something completely different, normally something most people would consider unpleasant or embarrassing, such as pictures of male genitalia.
Tommy thought he downloaded a .rar containing the full version Assassin's Creed, but instead it was hundreds of pictures of gay porn. Tommy ended up getting a rar-full of dicks.
