Flip pins over (4)
I believe the answer is:
spin
'flip' is the definition.
(thesaurus)
'pins over' is the wordplay.
'over' is an anagram indicator.
'pins' with letters rearranged gives 'SPIN'.
(Other definitions for spin that I've seen before include "Rapidly rotate" , "Make up a story" , "Fish" , "Slant put on news etc" , "Give it a whirl" .)
