hypocondriac
The opposite of hypercondriac. Instead of always thinking they are sick, they will brag they haven never been to a doctor and/or dentist.. Eat unhealthfully and feel no shame about it and will tell you so. Could be used as a slur against someone's lifestyle habits you do not approve of. It is a rather classist slur
My friend just bragged to me he eats fast food everyday and is not fat. He doesn't care what it will do to his heart health. What a hypocondriac.
