Get cold feet什麼意思

"Get cold feet" is an English idiom that means to become suddenly afraid or nervous about something, especially just before doing it. It often refers to a situation where someone feels anxious or has second thoughts about a commitment, such as getting married, making a big purchase, or taking a new job. The phrase suggests that the person's feet have gone cold, symbolizing a loss of warmth or courage.

For example: "John was all set to propose to his girlfriend, but he got cold feet at the last minute and couldn't go through with it."

In this example, John had decided to propose but became suddenly afraid or nervous just before he was going to do it, so he changed his mind and didn't propose after all.
