look up any word, like kappa:

1 definition by Dr. Albert Einstein

(noun) - a physical force acting upon an object that opposes centrifugal force, thus forcing an object to the center. The word originates from the roots centri (meaning center) and petal (like a flower). Centri.....petal, kind of like Sesame Street.
Nick tried to tell is friends at the Harley Davidson Cafe that centripetal was a word, but because nobody believed him, he had to go home and let google prove his point for him.
