Invented in Mr. Kane's Geometry class around the beginning of 2005 by Michael Phan (asian), and Cameron Mike (black). When the two were arguing, Michael mocked Cameron and called him a chank, because when Cameron says chink with his Koramo like voice, it sounds like chank. Just one year later the word was widely used throughout Fremont CA, and is still spreading. The #1 victim of this word is Michael and Cameron's friend, Luc Mai. This word is mostly used to make fun of asians, but now anyone can be called a chank.
Luc you chank, put your shirt back on.
Shut up chanker stanker!
Get your chank ass out of here.
