Dance clubs dealing with gear regularly going missing (5)
I believe the answer is:
conga
'dance' is the definition.
(conga is a type of dance)
'clubs dealing with gear regularly going missing' is the wordplay.
'clubs' becomes 'c' (abbreviation in card games).
'dealing with' becomes 'on'.
'regularly going missing' indicates alternate letters.
The alternate letters of 'gear' are 'ga'.
'c'+'on'+'ga'='CONGA'
(Other definitions for conga that I've seen before include "Cuban dance of three steps followed by a kick" , "Dance of 3 steps and a kick by people in single file" , "Latin-American dance" , "Circuitous line dance" , "Chain dance" .)
