Antimeme Tee

adj; "antimemetic" A piece of information that is inherently self-censoring by its very nature (e.g.; passwords, secrets, classified information). Though practically a useless term for our real world, within the SCP fandom and subsequently, the in-universe fiction of the SCP Foundation itself, it refers to anomalies that cannot be remembered (neither within short nor long-term memory) by anyone's mind even after it has already been perceived multiple times. This effect could also extend to the anomaly's appearances, recordings of it (of any kind), and even the effects and/or consequences within reality that the anomaly has caused, inadvertently or not.
