I do not think that word means what you think it does: Blurge

As I purged myself of various disgusting cold-produced effluvia last  night, the word that came to mind was "blurge."  And I began to wonder, as I often do when I have many things to do and not enough time to do them, if "blurge" is an actual word and if so, what it means.
As a matter of fact, it is a word and thanks to the Urban Dictionary, I now know what it means and will never use it again. A "blurge" is a blow job given by a woman who has just vomited.
I know, I could have gone the rest of my life without knowing that.
Who thinks this stuff up?
