In no time flat
Meaning
To do something extremely quickly, almost instantaneously, and without any delay.
Origin
The phrase "in no time" has been around for centuries, simply meaning "very quickly." But it was the addition of the emphatic "flat" in the early 20th century that supercharged its meaning. Imagine a surface so perfectly flat that there's no friction, no bumps, no delays whatsoever—just pure, unadulterated speed. This "flatness" evokes a sense of absolute instantaneousness, like an object moving "flat out" at maximum velocity or a statement delivered with "flat" certainty, leaving no room for doubt or delay. This snappy, almost onomatopoeic enhancement took hold in American English, particularly in the mid-20th century, becoming a popular way to describe something accomplished with remarkable, almost unbelievable, swiftness, as if time itself had been flattened out of existence.
