Sneak-Attext
When someone sends you a text pointing out something that's wrong or doesn't quite fit in the scenario, but at the same time you act as if you never got a text because it's rather personal.
Yo we were on the bus with this guy we just met and he was a little too social, so my friend Novian sent me a sneak-attext saying not to mention where we were headed off to when we got off. If he were to follow us, things would've gotten real awkward.
