Three fellows in line, each wanting last dance (3-3-3)
I believe the answer is:
cha-cha-cha
'dance' is the definition.
(type of dance)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cha-cha-cha that I've seen before include "Latin American dance - 1-2-3 rhythm" , "Ballroom dance" , "A Latin American dance, very repetitive" , "Latin-American dance" , "Latin American dance, sounds trebled" .)
