When a woman has hard nipples, it usually takes place in cold office buildings. It refers to the thermometer that pops up when your turkey is done cooking
"Hey girl, your turkey's done."
An expression to point out that a female in the room has erect nipples. Typically used for a woman with particularly large nipples like those of a temperature indicator on a turkey in the oven that pops up when the bird is done.
(as a girl with high beams
in a tight turtle neck walks by...)
Dude, the turkey's done!
When a girl has hard nipples.
