1. Slang for a thin, pointy penis. Practically useless for anybody but the owner of said Sharpie, the common response to inquiries regarding one's Sharpie is "None of your business."

2. A brand of permanent markers used to write on almost any surface with pinpoint "sharpness", thus the name "Sharpie".
Joaquin: "Hey, Rob, do you have a Sharpie?" (referring to a marker)

Rob: "Y'know what, Joaquin, that's none of your business." (referring to his penis.)
