Text Sniping

The act of noticing someone who you know in a crowd or some other public situation and sending them a text from an unknown position referring to something which they are doing at the time e.g. "Reading by the lakeside, how very avant garde" this simulates the 'shot out of nowhere' effect of a sniper.

<Maria is having coffee>
Scott: (unseen by Maria) <observes Maria from a distance and sends a text> "ooh two sugars, bit of a sweet tooth aren't you?"

Maria: <checks phone and begins looking around aimlessly> replies "where are you?"

Scott: "I'm text sniping, so you have to guess"
