Fisherian runaway is a popular meme in the [[manosphere]] used to argue women's mate choices may be maladaptive, resulting in excessive emphasis on courtship and selecting exaggerated anti-social and useless traits and inciting male competition. Fisherian runaway is often misunderstood to refer to exaggerating appearance as lifestyle choice, but it actually refers to ''evolving'' more exaggerated appearance over many generations. However, the sexual preferences that result from that can motivate extreme body modifications like breast enlargement, hormone supplements and bodybuilding. | |||
