The phase in the relationship where two people are more than friends but not together. They are usually playful and constantly flirt with one another but have not held hands or kissed. Most commonly known as the "just talking" phase of a relationship.
I met a guy online. We met a couple of times but we aren't serious or anything. I would say we are in a ludicacious relationship.
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?"
