The spelling of "hast fling" can be a bit confusing as it is a phrase composed of two separate words. "Hast" is spelled with the letters "h-a-s-t" and is pronounced /hæst/, with a short "a" sound as in "hat". "Fling" is spelled with the letters "f-l-i-n-g" and is pronounced /flɪŋ/, with the "i" sound as in "sit". Together, the phrase is pronounced /hæst flɪŋ/, meaning a quick and impulsive action.
