Walk into any casual conversation or scroll through social media, and you’ll likely hear phrases like “I’m so OCD about my desk,” or “That show ending left me depressed.” Often, people use clinical terms as exaggerations for everyday quirks or feelings. No harm is usually intended – it’s become common slang to describe being neat, sad, or distracted. However, this habit of borrowing mental health diagnoses as figures of speech can have unintended consequences. What might seem like a light-hearted comment to one person can come across very differently to someone who actually lives with that condition . In fact, casually using these labels can trivialise complex conditions, turning serious disorders into throwaway adjectives. Before we brush off these concerns, it’s important to understand what OCD, ADHD, and depression truly involve and why using these terms flippantly can be problematic.
