Often abbreviated as BHS, Big Heart Syndrome is where a person has such a big heart that they tend to care too much about others and are usually quick to fall in love/suffer a broken heart. Those afflicted with BHS also try to "fix" people or "fix" others current situations.
I look at the situations some of my friends and family are in, and all I can do is cry. My Big HeartSyndrome is acting up.
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?"
