Responded to something with too much emotion or intensity, making a bigger deal out of it than it deserved.
From 'over-' (prefix meaning excessively) plus 'react' (from Latin 'reactus,' to act in return). This compound word is relatively modern, reflecting 20th-century psychology's focus on emotional responses.
Psychologists study overreaction through 'amygdala hijacking'—when your brain's emotion center takes over faster than your logical thinking, which is why you might say something mean you don't mean in a split second!
Emotional overreaction narratives have historically been gendered—particularly women labeled 'hysterical' or 'overemotional.' The term itself is neutral, but application bias persists in how men vs. women's responses are interpreted.
Specify the objective trigger and impact rather than labeling reactions; avoid dismissive framing that might disproportionately apply to marginalized groups.
["responded intensely","escalated beyond the trigger","responded disproportionately to the situation"]
