During a dialogue or monologue, one speaker's line has a single word repeated for dramatic effect, either by the same person (to emphasize his point) or by the other (to undermine said point).
Compare Department of Redundancy Department, where an item is listed repeatedly for comic effect, Parrot Exposition, where multiple characters utter the same word or phrase for similar reasons, and Ironic Echo, for the entire sentence. See also One-Liner, Name... One-Liner.
Not to be confused with Punctuated! For! Emphasis!
