... wild hot rod fans etc. (3,2,5)
I believe the answer is:
and so forth
'etc' is the definition.
(both can indicate a list continues)
'wild hot rod fans' is the wordplay.
'wild' is an anagram indicator.
'hot'+'rod'+'fans'='hotrodfans'
'hotrodfans' with letters rearranged gives 'AND SO FORTH'.
(Other definitions for and so forth that I've seen before include "imagine what follows" , "Along with other things" , "Et cetera" , "implies others of the same type" , "etc." .)
