Deplorably overact, skipping rope's end in frolic (6)
I believe the answer is:
cavort

(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cavort that I've seen before include "Dance with glee" , "be frolicsome" , "'Lark about, romp (6)'" , "Frisk and frolic" , "Caper about excitedly" .)
