Alternatively, another name for the penis.

Square Pink Ninja is, well, imagine if Chuck Norris merged with Bruce Lee, only smaller and Pink. He pops up in random pictures, and appears in a small comic strip on Myspace. After only two weeks, Square Pink Ninja already had over a hundred and fifty fans. He is the intellectual property of Dash and Speedy, and was created during the summer of 2008.
