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.

The Source from where it's coming from remains a Mystery

certain type of cult activity in ancient greek, it was well guarded secret, cult members committed rituals and drank several drinks (wine),and likely mushroom and plant extracts like junkies nowadays and they saw interesting hallucinations about their god dionysos.
Dionysos mystery and demeter mystery were kept in secret. Who broke the silence oath, had to die.

1) An object of romantic or sexual interest. Doesn't need to be only a hard-to-reach attraction--can also be a boyfriend/girlfriend. Usually, a mystery is a boy when referred to in a group of girls.
2) A euphemism for just about anything.
1) Girl 1: How's your mystery, love?
Girl 2: Oh, just spiffy. We were mackin' yesterday.
Girl 1: I'm totally jellin'... I wish I had a mystery.

2) Oh, fuck! I just stepped in some mystery!
