Porridge Knickers 

A condition that results in the soiling of female undergarments due to extreme sexual excitement. This results in the kickers appearing to have a porridge like colour and texture stained into them.

I brought a durty yoke home from the Lodge last night and she was foaming at the gash - serious case of porridge knickers lying on my floor in the morning.
