- The grim reaper of cocaine addiction.

This term was offered up for the first time (I belive) in the Steely Dan song 'The Boston Rag' in 1973.
"Will you still have a song to sing when the razor boy comes and takes your fancy things away? Will you still be singing it on that cold and windy day."

A person, not just a male, that insists on always having a blade, be it a simple pocket knife to a straight razor. This person further insists that he can fight with it, and fight well.
We were chilling at our spot when my ex showed up. I was gonna tell her off but she is dating a razorboy.
