saccades

so i had a quiz in my psych class today and i had to define a bunch of terms. there was one that i really didnt know; "saccades". i remembered that my professor said that he gave points for creative answers, and i really didnt know what "saccades" meant so i said; "a samll inscet that decsends in masses on Washington D.C. and the surrounding areas once every 17 years." i havent gotten the quiz back yet but im hoping that he thought that was funny.
