Sure! Let's break down the word "iceman."
The word "iceman" can refer to two main things: 1. A person who cuts and delivers ice: In the past, before refrigerators were common, icemen would harvest ice from lakes and deliver it to homes to keep food cold. 2. A slang term for a professional killer: In some contexts, especially in crime-related discussions or movies, an "iceman" can be used to describe someone who is very skilled at killing, often in a cold and unemotional way.
In literature or film, "iceman" may be used metaphorically to describe someone who remains calm and detached in intense situations, often relating to their work or actions.
Aside from the primary meanings, "iceman" can also be used in a broader sense to refer to someone who is cool or unemotional, although this is less common.
There are no direct idioms or phrasal verbs specifically using "iceman," but you might come across phrases like "cold as ice," which implies someone is emotionally detached, similar to the "iceman" definition related to a killer.
