Expression: Tomber dans les pommes

Meaning: to faint, pass out

Literal translation: to fall in the apples

Variation: partir dans les pommes (to leave in the apples)

Notes: The French expression tomber dans les pommes is a cute way of saying that someone fainted, but I wish I knew why/how apples are related to a state of unconsciousness.* This strange link continues in the equally informal expression rester dans les pommes - "to (continue to) be out cold, to remain unconscious."

*According to Le Grand Robert, the probable origin is George Sand's être dans les pommes cuites, a play on être cuit (to be exhausted) in Rey et Chantreau, but that still doesn't explain what apples have to do with anything.

Example:
N'ayant rien mangé depuis plus de 12 heures, elle est tombée dans les pommes.
Not having eaten anything for more than 12 hours, she passed out.
