Walk like a vagrant (5)
I believe the answer is:
tramp
I believe this is a double definition.
'walk' is the first definition.
(tramp is a kind of walk)
'a vagrant' is the second definition.
(thesaurus)
'like' acts as a link.
(Other definitions for tramp that I've seen before include "Live as a vagrant" , "I usually walk" , "Itinerant" , "Go heavily" , "Vagrant - cargo ship" .)
