Jazz dance (4)
I believe the answer is:
jive
'jazz dance' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for jive that I've seen before include "Jerky, jazz dance of the 1950s" , "Style of fast dance music" , "Swing music; dance" , "Deceptive talk" , "Lively dance" .)
