Get the Fatty Mc Fat Fat Fatty Fat Dog Fat mug.
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.
*large bang in the basement and weird noises*
Jim: What the hell was that Steve?
Steve: Oh no, oh no!
Jim: What dude what's wrong?
Steve: Fat Cancer Dog is here! we gotta get outta here!
FCD: Clingyyyyyyyyyyyyyy >;)

Get the Fat gay dog mug.
An Australian term that applies to red headed people, similar to "Bluey", in this case pointing out that the person looks like a semi-erect dogs penis (fur coloured with red lipstick protruding from the end). An extreme term of endearment.
"Hey Dog Fat!! Did you know red heads have no soul?"
