A vile creature. He is bald and full of buttery chub lard. He is currently fat and living around the Southeast Los Angeles area, specifially Whittier, California. He also has a shotgun wound to the forehead because someone once mistaked him for a zombie. He (or it) lurks in high schools and abandoned houses where asians clean constantly. His call can be heard miles away. His most heard one being, "FCD is here" FCD is the short way to see it. He is very dangerous and should not be taken lightly. If you call his name he will manifest as an inanimate object and do things to you that are far beyond inhumane. He usually envelops you with his fat or wraps his soggy nipples around you. I personally have spotted him along with my friends. Please be careful. FCD is all too real. Clingy. that is all.

Jim: What dude what's wrong?

FCD: Clingyyyyyyyyyyyyyy >;)

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.
