look up any word, like spook:
A person, usually male, who has a set personality for each person(s) in his life. A double kid may be one type of kid with his mother, one with his father, one with his friends, etc.
Steve was a real double kid. When he was with his mother, he would help old ladies cross the street. At night, when he was with his friends, he would rob innocent people for their money.
