On the edge of Eendrachtsplein in Rotterdam is a sculpture made by Paul McCarthy in 2001. He called it Santa Claus.
Since then it has been popularly nicknamed “Kabouter Buttplug” or the “Buttplug Gnome.” McCarthy said the object is officially a stylized Christmas tree and meant to be a comment on consumer culture. Maybe if he had painted it green and added some ornaments…
Anaalplug according to Google Translate. Or is it one of those international words like taxi and hotel?
