Step back in disgust out of cow's droppings (3)
I believe the answer is:
pas
'step' is the definition.
(I know that pas is a type of step)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pas that I've seen before include "step on stage" , "Ballet duet" , "Dancing step" , "Type of sausage" , "Dance step" .)
