A person who’s fat that is strong as well only because of said fat
The fat nigga strength term only really ever applies when physical altercations occur such as a tug-o-war; a fat man vs an average man. The AM will have to maybe pull 350+ pounds while the FM will only need to pull around 200+ which is way easier since all you’d have to do is fall backward and the AM will only feel even more weight which 350+ pounds is already so much which causes the FM to win and the AM to lose simply because he weighs more. So the FM has fat nigga strength
