To stop someone from ruining your plan and calling or asking someone else for help
Push one's car off the road
My dad didn't wanna make the hot dogs for Anna's birthday tomorrow, so I pushed his car off the road and asked my grandpa to get me the stuff to make the hot dogs instead.
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?"
