Clips of three gossips from tea dance?
I believe the answer is:
cha-cha-cha
Can you help me to learn more?
(Other definitions for cha-cha-cha that I've seen before include "A Latin American dance, very repetitive" , "Latin American dance - 1-2-3 rhythm" , "Latin American dance, sounds trebled" , "Latin-American dance" , "Ballroom dance" .)
