It often times reffers to the butt-hole. Its shape and color resembles what you would expect to see in a star-fish covered in chocolate. This word originated back in 1847 by a scooba-diver. You could use this word in a work safe manner and it will not occure to anybody that you are being a total Ass Hole.

Get the chocolate star fish mug.
Is a gay euphemistic innuendo to refer to an anus. Usually used in a context where one would like to rim someone. It's metaphorical to the orifice of the human rectum that looks like a star-fish and is darker in color than the rest of the skin.
So, me and David fooled around last night, it wasn't long before I ate his chocolate star-fish... Yum!
