The morning after, the recipient of a frixing will almost certainly suffer a sore head and embarrassment.
And confusion. He/She will probably have no idea who had been involved in the frixing and they dare not ask around through fear of asking an indivdual who was not party and completely unaware of the incident.
So the frixed person is left to speculate. And worry.
