The feeling that you're using sandpaper despite the fact you've purposely gone out and purchased the most expensive, softest, quadruple ply toilet paper that you could afford.
This feeling often occurs after overindulgence on spicy foods, or curry's such as vindaloo.
We had a heap of curry left over from the party on the weekend and I've been having it for lunch the last three days and now I've got the worst case of grindaloo
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?"
