Cuntnesia is the act of forgetting the cunt like actions you have performed in the past. People suffering from cuntnesia actually believe that they have never done anything wrong in the past and that those who remember their bad behaviour are the ones with problems. Cuntnesia, if left untreated, can lead to the formation of cult like groups that gather near water, hide under bridges, and consume freezer burnt sausages.
'Camnesia' is what occurs after one has done something on webcam one wishes he/she had not- especially beaver shots and self-violation.
Heather was totally claiming camnesia until Justin started posting webcaptures of her with her arm up her snatch. Then Heather just sort of...disappeared.
