College housing (4)
I believe the answer is:
dorm
'college housing' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dorm that I've seen before include "Sleeping quarters (abbr)" , "Boarding school bedroom (abbr)" , "Communal sleeping place (colloq.)" , "Where kippers might be" , "where many crash" .)
