A sharp pointy object located at the end of a finger. (In some cases, there have been reports of the stated object appearing at the end of toes. However, this statement cannot be confirmed as there is currently no proof of the named existence.) Often very sharp, the above substance can be used as a weapon. (Said cases HAVE been reported.) If you find yourself growing these strange objects, please note that yearly trimming should be practiced for your own safety, lest you dig them into your own flesh by mistake. Usually, pain follows. However, this cannot be confirmed either, as no real cases have been reported of this strange action.

Risky game of chance, typically played by the lower classes or students, where a much-needed visit to the toilet is followed by the depressing realisation that there is a very limited amount of toilet paper at the user´s disposal.
Guy 1: "Last night, Mandy invited me round for a free manicure as part of her beautician´s course."

Guy 2: "Wow, she is so hot. How did it go?"

Guy 1: "Pretty well until it became abundantly clear that I play the Fingernail Lottery every week."

"Such was my urgent need, I locked the toilet door in great haste, lowered my britches and dropped some friends off at the pool. Only then did I note the dire lack of toilet tissue. My heart sank in the sad knowledge that I would have to play the Fingernail Lottery."
