Something that has been left in the toaster, such as a bagel, poptart, or (especially) toast. It was cooked, likely for the intent of eating, but was neglected for days for whatever reason. This is usually performed by siblings who have plenty of time to eat it, or parents, who keep their coffee in the microwave for days without drinking it. This could technically be considered toasterbread too.
Hey, who's toast is this? It's getting cold, dont you want it? (one week later) Nobody ate the toast... now it's toasterbread. -_-
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?"
