The act of sneaking closely up behind someone and exhaling a deep breath of hot air into their hair. Usually done to a coworker in an office environment but also appropriate in situations where there are people to witness the act.
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.
