Fat girl rage is so utterly transparent: projected self-loathing about their inability to control what they eat. They don't despise themselves because they're fat, they despise themselves because they have so little self-control they choose ice cream as being more important to them than their health and appearance. They would literally become suicidal if all that frustration and anger remained self-directed, so in order to cope they are forced to project it externally. Hence, fat girl rage.
