How it's used
Carries a strong connotation of annoyance or bewilderment, implying that the sudden action is unprovoked or lacks a logical reason. It is frequently used to express frustration when someone disrupts a peaceful moment or makes an abrupt, bizarre request. Unlike neutral terms for suddenness, this phrase highlights the jarring nature of the event.
Examples
He showed up out of the blue to find me and gave me a fright.

Common mistake
Avoid using this in formal writing or professional settings, as it is strictly colloquial and carries a slightly informal, emotive tone. It is not interchangeable with neutral adverbs like 突然, which can be used in any context.
