Note: "Forbidden fruit" is a metaphorical phrase originating from the Genesis narrative concerning Adam and Eve. In the narrative, the fruit came from the Tree of Knowledge of Good and Evil and was eaten by Adam and Eve in the Garden of Eden.

As a metaphor, the phrase typically refers to any indulgence or pleasure that is considered illegal or immoral. It may also refer to something being potentially dangerous or harmful, particularly
relating to human sexuality.

In Western Europe, the fruit was often depicted as an apple. The larynx in the human throat, noticeably more prominent in males, was consequently called an Adam's apple, from a notion that it was caused by the forbidden fruit sticking from Adam's throat as he swallowed it (textual source: Wikipedia).
