Excessive talking, sometimes to the point where it gets boring and drags on for way too long, aka rambling.
It's a slang word used by the company Team Volven.
"Bro the CEO talks so much I had to make a definition for rambling with his name in it, he's always jackaling about nonsense that has nothing to do with the previous topic."
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?"
