Guy manicure

A guy's manicure. Involves cleaning out fingernails out using a switchblade or pocketknife. Not for most women. Women who can do a guy manicure usually score higher with men on a coolness-factor. All guy manicures are self-performed. Never, ever, ask for a guy manicure from someone else.
