death warmed up

The idiom "death warmed up" is often used to describe someone who looks extremely ill or exhausted. It is believed to have originated in the early 20th century, although the exact origin is unclear. The phrase is commonly used in British English, but it can also be found in American English and other English-speaking countries.

It is thought that the idiom derives its meaning from the literal interpretation of someone being so close to death that they are starting to regain some warmth. However, it is important to note that the expression is not typically used to describe someone who is actually near death or in a life-threatening condition.

When used, "death warmed up" is often employed in a lighthearted or exaggerated manner to emphasize someone's appearance of extreme tiredness or sickness. It adds a touch of humor to describe someone who appears as if they have been through the most dire circumstances imaginable.

The final related idiom is "dead of winter." This phrase is used to describe the coldest and most severe part of winter. It suggests that winter has reached a point where it could be described as dead, emphasizing the extreme cold and bleakness of the season. This can be connected to the idea of someone who looks as if they have been through the worst of times, as captured by the expression "death warmed up."
