A seemingly illicit substance, usually of a white and powdered composition or occasionally with a yellowish hue.
A mystery bag is usually found in a zip locked baggie during clean up following a rave, a chance but rather delightful encounter. More deliberate encounters may come from a Boom Boom partyboy in the fall out of a festival... Boom Boom will want to keep the party going through Monday.

Referring to an individual defecating and/or on one's self or others. May or may not be sexual. Also can have random occurrences, often fun to do at a water park with butt pirates. It is an insult to be dubbed a mystery nugget to African Americans. To be called a mystery nugget one should respond with a smile.

A game where a man docks with multiple men and allows them to ejaculate inside of his dick. He then goes and has sex with a girl and releases all the cum inside her. When she becomes pregnant, it will be a mystery as to whose baby it is.
Did you hear what happened to Dawanna? She got mystery baby by Jose, Jawann, Pedro, and Martinez and now doesn't know who the father is.
