搓澡 refers to the practice of scrubbing the body with a damp washcloth or towel in a public bathhouse to remove dead skin, a common service in northern Chinese bathhouses. It is a separable verb (离合词): the verb 搓 and the object 澡 can split when inserting measure words, durations, or complements, e.g. 搓了一次澡 ('scrubbed once'), 搓了半个小时澡 ('scrubbed for half an hour'). The person being scrubbed is introduced with 给: 给我搓澡 ('scrub me').
