The term "Mickey" is a slang phrase that means to deceive or cheat someone, usually in a game or situation where chance plays a role. It can also refer to an act of deception or trickery intended to gain an advantage over another person. The origin of the word is unclear but it may be related to the name Mickey Rooney, who was known for his fast talking and hustling ways in movies such as "The Stuff Dreams Are Made Of" (1978).
