The phrase "get hot under the collar" is an idiomatic expression used to describe someone who becomes angry or upset. The word "collar" is pronounced /ˈkɒlə(r)/ in IPA phonetic transcription. The spelling is derived from the Old French word "coler," meaning "neck," which was adopted into Middle English as "collare." The vowel sound in "collar" is pronounced like the "a" in "father," represented by the symbol /ɒ/, followed by the "L" sound and the schwa sound /ə/. The phrase's spelling is fairly straightforward and reflects its historical roots.
To get hot under the collar means to become angry, agitated, or upset about something. This idiom typically refers to a sudden emotional reaction, often triggered by a particular event, situation, or person's actions or words. When someone gets hot under the collar, they can display visible signs of frustration, which may include redness in the face or neck, sweating, increased heart rate, or a raised voice.
This expression is derived from the physical reaction of the body when experiencing intense emotions, specifically anger or annoyance. The phrase suggests that the heat generated by these emotions can cause discomfort or irritation, metaphorically likening the emotional response to the sensation of wearing a tight collar that becomes hot and bothersome.
Getting hot under the collar is often used in informal contexts and implies a temporary outburst of anger or irritation rather than a sustained state of rage. People may become hot under the collar when they feel unfairly treated, when they encounter incompetence or rudeness, or when their beliefs or values are challenged. It is a way to describe someone losing their composure and reacting emotionally to a perceived offense or injustice.
In summary, to get hot under the collar is to become angry or agitated, typically in response to a specific trigger that prompts a sudden emotional reaction.
