In a jiffy means very soon or very quickly, usually in informal and cheerful speech. In poetry, it can bring lightness, domestic immediacy, or comic reassurance to scenes of waiting, service, childhood, or everyday promise. The phrase is less dramatic than “in a flash”; it suggests quick practical action rather than sudden revelation. A poet may use it to characterise a speaker as brisk, kind, evasive, or naively confident. It is useful when colloquial time contrasts with deeper emotional delay.

In a jiffy means in a very short time, with a light, informal tone. In poetry, it can make a speaker sound cheerful, brisk, comic, or reassuring. The phrase works best in conversational verse, children’s poetry, or dramatic monologue rather than solemn lyric. Students should notice that it reduces waiting by promising quickness. It can be used ironically when the promised jiffy stretches into delay, impatience, or comic frustration.
