Mystery

A brilliant mind, made for bettering the world. She sees into the depths and pulls people to the light. She is unknown while knowing everyone. She hides in the caverns of her own soul only to become more extravagant. She is beautifully and intriguingly loyal. She is a mystery.

something you have to find out, or you dont know and never will.
Or something sexual, that you don't know, and await to find out.

The term used to describe the act of when an individual takes a shit in the tank of a toilet, usually done as a result of revenge or a practical joke played on a less favourable person. When they flush the toilet, the shit is filtered through and exposed into the basin, where it creates a foul smell and a dirty basin.

Is someone that no matter what would you do, you won't be able to understand them, or to get straight answers, he is the guy/girl who is friends with everyone, can talk to whom they want, but still shares no secrets, no pain, nothing with someone else than themselfs... he is the guy that walks with his hands in his pockets, looks arround once a while, doesnt talk much, probably smokes, and have more than one talent, but doesnt use it to draw other's attention..
