Swimmers driven crazy in wild kiss (4,6)
I believe the answer is:
skin divers
'swimmers' is the definition.
(skin-diver is a kind of swimmer)
'driven crazy in wild kiss' is the wordplay.
'crazy' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'wild' indicates an anagram.
'driven' is an anagram of 'ndiver'.
'kiss' with letters rearranged gives 'skis'.
'ndiver' put within 'skis' is 'SKIN-DIVERS'.
(Other definitions for skin divers that I've seen before include "they're seeking depth, not afraid to be wet?" , "underwater explorers" .)
