Dremory is the word used to describe somebody's recollection of a drunken night out from the person who can't remembers point of view - if you can't remember it never happened! Dremory!
Friend one- Last night you were so shitfaced you took your pants off and air humped a lamppost!
Friend two, nope, wasn't me, that must have been a dremory!
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
