A telemarketer or other phone-obsessed "reptile" who incessantly calls everyone in da phone book, either to feed them some hard-sell song-and-dance, or just to waste their time wif a lotta bu**s**t jibba-jabba.
I am on the National So-Bot-Call List, but since when do those money-hungry crocodials follow da law???
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.
