Ffk syndrome aka former fat kid syndrome is when a person who was fat as a kid, teenager, or just in general and lost a lot of weight. Their body may have slimmed out but their minds are those the same as a fat kid. They seem to recognize their unhealthy thoughts and surpress them daily and throughout their lives trying to continue a healthy life.

A person who, in the past was fat and/or utterly unattractive, but now is considered attractive by society, yet still retains the mental, and emotional status of a fat kid and therefore does not understand social cues.
