1 A whirlwind, whirlpool, or similarly moving matter in the form of a spiral or column.  An extreme version of vorticity is a vortex. The vortex is a spinning, cyclonic mass of fluid, which can be observed in the rotation of water going down a drain, as well as in smoke rings, tornados and hurricanes.
In the 1950s and 1960s poopy actually described those who were like a poop, which meant a stupid person. The first appearance of poopy cited by the OED is one of these usages, from a 1957 issue of The New Yorker, which described âsome nice old poopy elder statesman.â.
Some have speculated that the word is a nonsense word that combines elements of other words implying ignorance or stupidity. The word ninny, for example, was a corruption of innocent, meaning a naÃ¯ve or gullible person. In Dutch, the word poop was often used to describe a fool. It is conceivable that the originator of nincompoop was seeking to combine several unsophisticated words into one nonsensical but descriptive word.
