Noun; A woman who was once a Murf-Beast, but is no longer one do your one night of drinking, and while blacked out you slept with her, transforming the murf-beast into a golden-cow.
As the morning sun came though my window the evil murf-beast was gone. in its place was a golden-cow...and the worst hangover I have ever had.
