A big dookie like a chocolate swirl ice cream sundae right on the head of an unknowing loser, creating the image of HAAJI from Johnny Quest. Thus the turdbin is born.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

When someone craps on your head with a long turd and a swirling motion. the result is a pile of dookie shaped like a turbin. hence: the name turdbin

Taking a mean shit on someone's turban
