Slimfastkow 

Usually a male name, but it can also be a name for fat girls who "try to loose weight, but can't".

Slimfastkow's are generally educated transgender satanists. This makes them a rare breed of humanoid and a refreshing breath of fresh air in any social situation. They're someone mega amazing and enjoy smoking weed, socializing, music, fighting for human rights and gorging themselves with children's dreams while they sleep.

I'm so glad I met Slimfastkow.

With a name like Slimfastkow, you know he has a sense of humor.

Yes, Slimfastkow is quite enjoyable.
