A textteaser is a person who loves to send texts. So much so that they make you believe they are your best friend. They will text you at all costs but never want to actually see you. They get gratification from the attention texting gives them but have little to no interest in being friends with the person they are texting.
Shawn is such a textteaser, we text everyday after work but he is always making excuses to hang out with me.
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?"
