A humorous remark with its orgins in sarcasm and mixed with scathing but more direct. With the probability to offend, it is typically derived from a previous upsetting action, situation or circumstances. Often with the explicit intention of making a point or to put somebody / something in its place.
Example of sorecasm.
"Can't wait for us to meet up & party again"
"Yeah its going to be ace. Maybe this time you won't make all those plans with me, then cry off last minute with lamefake excuses. Cos that worked great for me last time."
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.
