Medical Definition of bigorexia
: muscle dysmorphia
Most American men would do well to exercise more and improve their diets, but a small number … suffer from a condition psychiatrists call bigorexia, or muscle dysmorphia, in which they feel crippling shame and embarrassment about their perceived smallness.— Rebecca Keegan, The Los Angeles Times, 29 May 2011
