A cold fish
Meaning
An unemotional, distant, and unsympathetic person who shows little warmth or friendliness.
Origin
The human tendency to compare emotional states to animal characteristics is ancient. Fish, as cold-blooded creatures inhabiting an aquatic world, have long been observed as inherently lacking warmth, expression, and any apparent emotion. This primal perception of fish—silent, distant, and unfeeling—naturally extended into a metaphor for human temperament. By the 19th century, describing an emotionally detached or unresponsive person as "a cold fish" became a vivid and widely understood idiom, directly linking their perceived lack of human warmth to the literal coldness and uncommunicative nature of marine life.
Examples
- Despite his charming smile, many found the new CEO to be a cold fish, rarely showing any personal emotion or connection.
- She tried to befriend her new colleague, but he was such a cold fish that all her attempts at friendly conversation met with awkward silence.
