Put down another suncream tip? (3,2,2)
I believe the answer is:
rub it in
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for rub it in that I've seen before include "Unkindly emphasise" , "Remind or taunt someone about unpleasant fact" , "Remind person of unpleasant fact - during massage?" , "Harp on something distasteful to person not wishing to be reminded of it" , "Remind someone maliciously of an embarrassment" .)
