a euphemism for defecation, used in conjunction with 'little-boy' (i.e. urination). Commonly used as a noun, but acceptable in verb form.
I shouldn't have had that seventh enchilada. I've never had to take a fat-man so bad in my life.
I always fat-man before i go to work in the morning.

Get the fat-manmug. A woman who is over 130 pounds but still fights every day because she recognizes her self worth in school in the gym and at work. These females use heavy makeup and don't let there overweight lifestyle compromise there self worth. They fight through constant rejection and usually have a better personality than the good looking females because of it.
That girl over there dancing is definetly a fat queen most females that weight and with that much makeup would stay at home she's so confident!
