Tramp in wild parties (7)
I believe the answer is:
traipse
'tramp' is the definition.
(I've seen this in another clue)
'wild parties' is the wordplay.
'wild' is an anagram indicator.
'parties' with letters rearranged gives 'TRAIPSE'.
'in' is the link.
(Other definitions for traipse that I've seen before include "Plod - trek" , "laborious walk" , "Parties (anag.)" , "long tiring walk" , "Walk heavily" .)
