Laszlo, a stock trader from MMGinvest coined the term, "Moonboy" when referring to over-exuberance and unrealistic beliefs and bias by none professional investors who think their investment value will shoot up in price like a space rocket launch towards the moon. an analogy of an extremely lengthy distance upward into the sky then outer space reaching the moon surface. The "Moonboys" entire investment strategy is based upon convincing themselves and others to join them in their crusade to make their initial investment within an asset class and or security gain popularity in order to gain demand pushing higher valuations so the "Moonboy" can off-load their investment onto new buyers purchasing at much higher prices, as a result, gaining massive profits. This type of behaviour can be a result of greed and or desperation, common symptoms are never-ending conversations of becoming rich quick and or daydreaming about exotic sports cars such as Lamborghini's.

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
