Originally meaning one of the Olsen Twins, this has come to be descriptive of any jailbait. Someone under the age of consent who you would love to bone silly.

Disgusting little twins who are pure evil. Though they are rich, the will never be like me, the richest man in the world! Ha ha ha! You fail!
Thought the Olsen twins are rich from their product line of female articles and items, they will never compare to the high technological advancements of Windows!
