If you are guilty of turpitude, you should be ashamed of yourself. Turpitude is a word that represents depraved behavior. Prisons are filled with criminals who have engaged in acts of moral turpitude.
Turpitude comes from the Latin word turpitudo, which means "repulsiveness." Corrupt politicians get booted out of office for acts of turpitude, like taking bribes in exchange for lucrative government contracts. Turpitude often follows the word moral, and acts of moral turpitude are usually crimes that are unusually sick or corrupt.
