He rubbed his face in the wound

This beauty is a mash up of “rubbed salt in the wound” (make someone feel worse about something)  and “rubbed his nose in it” (remind someone of something one has done wrong).   Perhaps the speaker was reminding someone of a mistake and bragging about it at the same time.  Or maybe this is a new form of medical treatment?  A big thank you to Ed Brady for hearing and sending this one in.
