Particulars -- of the hokey cokey? (3,3,4)
I believe the answer is:
ins and outs
'particulars' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ins and outs that I've seen before include "signs on doors perhaps" , "Details" , "cabinet reshuffle?" , "parliamentary election result?" .)
