Does Your Team Maintain an F-Word List?

Ever noticed how some phrases kill a project faster than any deadline?

Every team has its own folklore. Some teams bond over memes, others over inside jokes, and some connect through the shared pain of quarterly OKR cycles. But there’s one thing most teams never discuss: forbidden phrases. I call these the “F-words.” Not the ones that get you in trouble on Slack, but the innocent-sounding lines that slowly break down trust, ownership, and teamwork.

Most teams don’t keep a list of these F-words. They really should.

What’s interesting is that the worst phrases aren’t usually aggressive. They’re gentle, polite, and sometimes even meant well. But as soon as they’re said, the mood changes. Responsibility fades, accountability disappears, and suddenly the project timeline is a blurry mess.

Consider the classic: “It was not supposed to happen.” It sounds harmless and even suggests fate was involved. But usually, it means no one takes responsibility and nothing is learned. A better way to say it is: “We didn’t predict this scenario. Here is what we’ve learned and what we’ll change next.” The second version encourages growth instead of helplessness.

Or take the common phrase: “This solution is bullet-proof.” As soon as someone says it, something always goes wrong. What people really mean is that they feel confident. A better way to say it is: “This solution covers our known risks, and here are the limits.” Showing confidence without arrogance is real leadership.

Then there’s “We do not need a plan B.” In most organizations, this isn’t a real strategy. It’s more like putting everyone in a tough spot. Smart teams know that having a plan B isn’t being negative; it’s just good practice. Skipping it leads to outages, missed deadlines, and last-minute weekend work.

And perhaps the most corrosive phrase: “It’s not my fault.” The moment this appears in a conversation, the focus shifts from solving the problem to distributing guilt. The issue stops being the issue, and the meeting becomes a legal drama. A much more productive approach is simple: “Here is the part I can own. Here is what I need from others.”

Another kind of problem comes from the hopeful phrase, “Let’s postpone this until things calm down.” The truth is, things rarely calm down. Not in tech, not in media, and not in any organization with more than a few people and a Slack channel. Delaying decisions only makes them harder. A better approach is to face the chaos and agree on what can be done now and what can wait, without pretending things will suddenly become peaceful.

Some statements seem harmless but show a deeper cultural problem. “We don’t have time for research.” This is often said just before a team spends weeks rebuilding something that a short user interview could have prevented. Research isn’t a luxury; it’s insurance against future problems. If time is short, the answer isn’t to skip research, but to scale it to fit.

Some phrases are outdated. “We’ve always done it this way.” This one belongs in a museum of old mindsets. Innovation often begins with the courage to ask why.

And then there’s the classic: “That’s impossible.” In product teams, this phrase doesn’t last long. Not because everything is possible, but because telling engineers something can’t be done is often motivating. A better response is: “Here are the constraints. Let’s explore options.” This keeps reality in mind, but leaves possibilities open.

Why does a team need an F-word list? Because language shapes culture. The phrases we use define how we work, handle mistakes, set expectations, and treat each other under pressure. Removing these phrases doesn’t just make teams more polite; it makes them more honest. The goal is clarity, not censorship.

A good F-word list is a shared agreement: “We don’t use language that shuts down thinking, hides responsibility, or kills momentum.” When people use better language, they make better decisions. And better decisions often mean fewer emergency meetings.

So yes, your team probably needs an F-word list. Not to police communication, but to protect the culture you want to build: open, practical, and a bit less dramatic.

And if someone says “That’s impossible” after you suggest the idea, congratulations. You’ve found your first item for the list.
