A sad addict.
1. Someone who plays too many MMORPGs and then comes into the office and precedes to tell everyone about the new potion or spell they've just aquired, thinking that anyone else would give a sh*t.
2. Just someone who is addicted to something (i.e. texting, facebook, msn) and their personality is zero.
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?"
