Get the PPU mug.
An internet phenomenon associated with the '/b/' random section of the 4chan imageboard. The users of this section anonymously logged onto Habbo Hotel, and using avatars of black people clothed in suits, along with a large afro, blockaded the Hotel's pool from entry while shouting 'Pools closed' to users trying to enter.

The phenomenon has since increased in popularity, and the GNAA and myg0t trolling communities have also started to participate in the blockades.
