Give someone the cold shoulder means to treat a person in a distant, unfriendly way. Usually, it means ignoring them, avoiding conversation, or showing clear social rejection.
Today, the meaning is straightforward. If someone gives you the cold shoulder, they are not being literally cold. They are acting as if they do not want your company.
The phrase is often linked to an old idea about hospitality. A welcome guest might be served a hot meal, but an unwelcome one might get a cold shoulder of meat, which signaled that it was time to leave. Experts do not fully agree on every detail of the story, but this is the most commonly cited origin.
- Social snub: She gave him the cold shoulder at the party.
- After conflict: After the argument, his friends gave him the cold shoulder.
- Workplace use: The team gave the new manager the cold shoulder at first.
So the phrase is about rejection and distance, not temperature. It is a vivid idiom for behavior that feels noticeably unfriendly.
