A "Timbitch" is a stupid, gullible person that goes to Tim Hortons after agreeing to buy coffee for 4 or more people, inconveniencing EVERYBODY that's waiting to buy coffee behind them.
You go toTim Hortons to buy 1 coffee and the person that's before you orders 7 or 8, making you wait longer than you should have to. THAT person would be a Timbitch...
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?"
