The word means to be scared of fat
people but
society changed into having or showing a dislike of or prejudice against Fat
people, which sounds stupid, and what are you supposed to do after having trouble with life for being fat, then what from there?
Word phobic meaning:
Person 1: If you are scared of fat
people that means you are 'fatphobic'
P2: Well I am Fatphobic then :D
Society meaning:
P1: I fucking
hate fat
people and I don't care that they are fat, they look ugly
P2: OMG! You are Fatphobic, I am posting this to twitter!
