A blowjob from an overweight or ugly female. Since the female lacks in looks she must make up for it by giving amazing head and committing acts during the blowjob not normally done. This word can also be used to describe head from an average or above average girl.
Example One: "She was hot and she gave me a fattie blowjob"

Example Two: "Got a fattie blowjob last night, near puked when I seen her naked though, but the head was worth it"
