Learn "Fluff" in depth →Mistake 1: Treating fluff as a verb meaning "pad" or "add filler"
The verb "to fluff" exists and can mean making something fuller or softer. However, using it to mean "add filler content" at work can be ambiguous, and the construction below sounds unnatural.
This version uses the verb in a less precise way.
"During the sprint retro, someone floated the idea of asking marketing to fluff last quarter's one-pager into a full case study before the conference."
This alternative uses a clearer verb for adding filler.
"During the sprint retro, someone floated the idea of asking marketing to pad last quarter's one-pager into a full case study before the conference."
For a more constructive editing request, use this alternative.
"During the sprint retro, someone floated the idea of asking marketing to flesh out last quarter's one-pager into a full case study before the conference."
Pad means adding filler and is usually not praise. Flesh out means adding useful facts and detail, which can be a constructive editing request. These verbs express the intended meanings more clearly than "fluff" does here.

Start the "Fluff" learning path →Mistake 2: Using fluff in formal or client-facing writing
Fluff is an informal word. In a report, client email, or formal review, it may sound too blunt even when the criticism itself is reasonable.
This wording is too casual for a professional client document.
"This section of your report is fluff."
This alternative gives the client more specific and useful direction.
"This section could be tightened to focus more directly on the recommendation."
Keep fluff for informal talk within your team. Choose more neutral wording when the audience or situation requires a professional tone.
Mistake 3: Using fluff as a personal criticism instead of feedback on the text
Fluff describes the content, not its writer. Aiming it at a person can feel like a personal attack and provides no useful direction.
A reviewer left one public comment on a draft: "Your writing is fluff." The writer did not revise it or send that reviewer another draft. Instead, she sent future drafts through a coworker.
Months later, the reviewer got clear feedback in a retro: "When you comment on the draft, name the paragraph. 'The second section restates the goal instead of answering whether we hit it — can you swap it for the actual number?' tells her what to fix. 'Fluff' just tells her you didn't like it." He could still use the word, but needed to apply it to the text. He also needed to suggest a specific fix instead of judging the person.
A related mistake: calling anything long "fluff"
Fluff concerns substance rather than length; confusing these qualities can remove necessary content.
An editor cut a twelve-page vendor risk review to four pages, calling it a fix for "fluff." The team using it objected within a day. Three removed pages contained the contract terms that explained why the vendor was risky. Without those details, the shorter version was unusable.
Length alone is not what fluff describes. Ask whether each sentence gives readers necessary information or helpful context. A detailed report can be fluff-free, while a shorter report can fail by removing essential details.
The underlying pattern
Fluff mistakes fall into two main groups. One uses an unclear or unnatural verb construction; the other involves inappropriate tone. Poor tone includes using a blunt word in formal writing or judging the writer instead of the content. Choose clear wording, the right setting, and the right target to avoid these mistakes.
