To "crash out" has multiple meanings depending on the context:
- In mental health and popular culture, "crashing out" generally means experiencing an emotional overwhelm or outburst where someone loses control or acts impulsively due to intense emotions like anger, stress, or frustration. It can involve yelling, making rash decisions, or emotionally breaking down after prolonged stress or burnout.
- It can also mean to fall asleep very quickly due to exhaustion, often after a long or tiring day.
- In some contexts, it can refer to quitting or ending something abruptly, like leaving an event or being eliminated from a competition.
- Additionally, in slang, particularly with some regional uses, it can mean acting impulsively and recklessly, sometimes with dangerous or unlawful behavior.
The most common current use in social media and informal speech tends to be the emotional loss of control or meltdown sense, often linked to stress and burnout.
In summary, "crash out" can mean to emotionally lose control or have a meltdown, to fall asleep quickly from tiredness, or more rarely to abruptly quit or behave recklessly depending on the situation.
