I mean, a Kathy moment is a sudden and involuntary (although depending on the source ya know, not altogether unexpected) release of ignorance which ya know, results in people talkin about how useless and stupid you are. I mean its not your fault you sleep all day ya know?
I was so tired that I slept past noon and couldn't remember where I put my cigarettes. It was such a Kathy Moment.
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?"
