Dance with tea - again and again (3-3-3)
I believe the answer is:
cha-cha-cha
'dance' is the definition.
(type of dance)
'with tea again and again' is the wordplay.
'with' says to put letters next to each other.
'tea' becomes 'cha' (cha is a type of tea).
'again and again' becomes 'chacha' (I can't justify this - if you can you should give a lot more credence to this answer).
'cha' put next to 'chacha' is 'CHA-CHA-CHA'.
Can you help me to learn more?
(Other definitions for cha-cha-cha that I've seen before include "Ballroom dance" , "Latin American dance - 1-2-3 rhythm" , "A Latin American dance, very repetitive" , "Latin American dance, sounds trebled" , "Latin-American dance" .)
