Be embarrassed (4,4)
I believe the answer is:
lose face
'be embarrassed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lose face that I've seen before include "drop in standing" , "Suffer a loss of respect" , "Suffer humiliation" , "Fail to preserve prestige" , "Suffer a reduction in prestige" .)
