A person who goes fishing for "Happy Birthday" wishes on social media. After receiving an initial round of good wishes (only because the people were reminded when they logged in), the wishfisher chums the waters with a "thank you" so others will remember to wish them a happy birthday, too.
Did you see Kyle's "Thanks for the birthday wishes" status update? He got 20 more happy birthdays because if it. He's such a wishfisher.
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?"
