When you have no recollection of the nights events due to consuming large amounts of the presription drug clonipin... More commonly used to describe the actual drug itself,

Origin: the combination of the drug (clonipin) and the effect it has when more than prescribed are taken (forgetting, blacking out, no memory of certain events or having memory lapses when trying to recall events from the night before)
