a sudden and often unpredictable change in one's mood · an abrupt shift in emotional state
Ever been super happy one minute and then inexplicably grumpy the next? 🎢 That's exactly when you're **having a mood swing**! This expression is perfect for describing those sudden, often temporary, shifts in your emotional state.
💡 **Pro Tip!** While 'to have a mood swing' often implies a somewhat unpredictable or even slightly negative shift, it can simply describe any sudden change. It's different from 'to be in a mood,' which usually means someone is grumpy or upset for a longer period. So, a mood swing is more about the *change itself*! ✨
