Hitched a ride with Mr. Clumsy (7)
I believe the answer is:
married
'hitched' is the definition.
(I've seen this before)
'a ride with mr clumsy' is the wordplay.
'with' is a charade indicator (letters next to each other).
'clumsy' is an anagram indicator.
'a'+'ride'+'mr'='aridemr'
'aridemr' is an anagram of 'MARRIED'.
(Other definitions for married that I've seen before include "having a wife" , "Spliced" , "Admirer (anag)" , "Closely linked" , "Espoused" .)
