Fat bitch logic (not to be confused with fat bitch feminism logic) is an easily observable anomaly that has overtaken certain parts of the internet and real-world social interactions, and can be found in varying locations (mostly social media) in which one is extremely defensive about ones own morbid obesity with fallacious logic. This list of excuses to be a fat shit range from ignorant with the "muh genetics" argument, to the extreme and even absurd "beautiful at every size" argument, where the fat bitch in question actually seems to take pride in the fact that they have serious pending health issues.
Random fat bitch: " I can eat whatever I want as long as I walk it off."
