look up any word, like thot:
 
1.
A large rotund man, with huge belly proportions and arrogant tendencies. A fatmingo resembles a flamingo through his pink attire and feasts on shiny shrimp. Fat-min-go

Can also be used as an expletive.
Wow look at that fatmingo, he has had many a shrimp today.

Holy Fatmingo!
