Rubs less randomly in city (8)
I believe the answer is:
brussels
'city' is the definition.
(Brussels is an example)
'rubs less randomly' is the wordplay.
'randomly' indicates anagramming the letters (I've seen 'roaming randomly' mean this).
'rubs'+'less'='rubsless'
'rubsless' with letters rearranged gives 'BRUSSELS'.
'in' is the link.
(Other definitions for brussels that I've seen before include "European Commission HQ" , "Belgian capital" , "Seat of the European Commission" , "Capital of Belgium" , "Release pent-up energy" .)
