The term used when referring to the genitalia of a practising nun. Nuns vow their chastity, therefore have a pocket that is forgotten about and never used.
"No sister Mary, I would not like to see your forgotten pocket, tis a sin"

"No, nuns can't have sex, theres no way you're putting that anywhere near my forgotten pocket"
