How it's used
Originally a scientific term for the speed of light, this has evolved into a popular slang expression for doing something with extreme efficiency or haste. It carries a playful, hyperbolic tone that emphasizes the urgency or speed of an action. It is most commonly used in casual settings among friends or colleagues to describe completing tasks or arriving somewhere.
Examples
He finished his meal at lightning speed and left.
Can you get it done for me super quickly?

Common phrases
complete at lightning speed
leave in a flash
Common mistake
Do not use this in formal writing or professional emails, as it is strictly colloquial slang. It is also not a direct substitute for the adverb 快 in every context, as it specifically implies a sense of sudden, high-speed completion.
