Get away from those people -- rough and common (3-2-3-4)
I believe the answer is:
run-of-the-mill
'common' is the definition.
(thesaurus)
'get away from those people rough' is the wordplay.
'get away' becomes 'run' (running is a kind of getting. I am not sure about the 'away' bit.).
'from' becomes 'of' (of can mean from or belonging to).
'those people' becomes 'them' ('they' refers to a group of people).
'rough' becomes 'ill' (rough can mean unwell).
'run'+'of'+'them'+'ill'='RUN-OF-THE-MILL'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for run-of-the-mill that I've seen before include "Mediocre" , "Everyday" , "Unexceptional" , "Bog standard" , "Ordinary" .)
