What is Fatty Mike?
1.
A teenage boy or man who isn't fat at all, and is actually quite attractive, but has self-esteem issues like that of a 15-year-old girl.
Fatty mikes are usually straight, but have EXTREMELY feminine qualities, like reading their girlfriend's YM & Cosmopolitan magazines, waxing pubic hair, and are weirdly emotional.
