A female who is known to have sexual relations with numerous persons and is known to be "easy" or "fast", and as a result of being a shone the female will become pregnant and usually will not know who the father of the baby will be, AND/OR she will come in contact with an STD.
She was labeled a shone, after the guys had seen her have sexual intercourse with four guys at the party.
This means the same as action but this is the shorter way of saying it. Someone who is shone is someone, most likey a girl who is a ho or an animal. She has a lot of sex with a lot of different people and everyone knows it.
