1. (n) A sterile aluminum foil bag used to keep an infant warm just after birth. It is standard equipment for emergency medical services personnel and is used as a precaution for most infants born in the field.
2. (n) A sexual act in which a man engages in intercourse with a woman in an environment that he has previously caused to have a very low temperature (ie, by turning the air conditioner way down). When the woman complains about the cold temperature, the man wraps her in aluminum foil and continues to have sexual relations with her. The foil, combined with the physical exertion of sex, causes her to become excessively hot to the point that she passes out from heat exhaustion.
