It is time. It is past time, actually.

We are four years into this forum's existence. Four years of discussions, arguments, breakthroughs, and legendary threads. And in all that time, across all those posts, we have never once agreed on a definition of the thing this entire community is built around.

What is the pump?

We all know what it feels like. We all know when it's happening. But we have never put it into words that everyone can agree on. This has caused problems. Specifically, it has caused:

- 847 arguments in which someone said "that's not what the pump is" and someone else said "yes it is" and nobody could settle it because we have no definition
- 12 subforum schisms where entire sections of the forum split off because of disagreements about what counts as a pump
- One near-forum-shutdown in 2002 when the thread "Is stretching a pump?" escalated to the point where PumpAdmin had to take the server offline for 48 hours

Enough. We need a definition. An official one. One that this community creates together, debates thoroughly, and ultimately ratifies.

I will start. Here is my initial attempt:

I acknowledge this needs work. It's more of a feeling than a definition. But it's a starting point. I believe we can do this. I believe it may take a very long time. I believe it will be worth it.

Reply with your proposals. Be respectful. Be thorough. The pump deserves a definition that honors what it truly is.

PumpMaster, I respect the initiative. Truly. But your proposed definition is — and I say this with love — poetic but insufficient.

"When the blood flows and the spirit follows" is beautiful. It would make an excellent tattoo. But a definition must do more than evoke — it must delineate. It must tell us where the pump begins and where it ends. It must draw boundaries around the phenomenon so that we can distinguish it from adjacent experiences (exercise euphoria, runner's high, mere fatigue).

The definition needs to capture three essential aspects of the pump:

1. THE PHYSICAL — the actual physiological event occurring in the muscles and vasculature
2. THE MENTAL — the cognitive and psychological state that accompanies the physical event
3. THE TRANSCENDENT — the aspect of the pump that exceeds the sum of the physical and mental, the part that makes pumpers describe it in spiritual or existential terms

My proposal:

I believe this is comprehensive and precise. It accounts for all three dimensions of the pump experience.

Guys.

TWO YEARS. We have been at this for TWO YEARS. There are 846 posts above this one. I have read every single one of them. We have had proposals involving philosophy, biology, quantum mechanics, one guy who cited the Dead Sea Scrolls, and a 3,000-word post that was entirely in Latin.

Here is my proposal:

That's it. That's the definition. It's simple. It's accurate. It covers what the pump is. You lift, you feel good, that's the pump.

I know what's going to happen. PhilosophyOfPump is going to say this is "reductive." Someone is going to say I'm "diminishing the transcendent dimension." PumpMaster is going to write a kind but firm paragraph about how the pump deserves more.

But I'm putting it out there. Sometimes simple is right.

[Editor's note: The next 400 replies were exactly what Dave predicted. The word "reductive" appeared 83 times. Dave did not retract his proposal. He never retracted it. To this day he maintains it was the best definition submitted.]

Friends. Pumpers. Forum members of every rank and era.

It has been 14 years.

14 years since I started this thread. 14 years since I proposed that we, as a community, define the pump. In that time, this thread has accumulated:

- 22,000+ replies
- 3 community votes (2009, 2013, 2017)
- 2 definition referendums (the first was invalidated due to ballot stuffing by the now-banned user PumpFraud99)
- 1 fistfight at PumpCon 2014 (between a physicalist and a transcendentalist; both were escorted out; both later apologized; both are still active members)

And as of today — as of the results of the August 2017 Community Referendum on the Official Definition of the Pump — we have reached consensus.

The vote was 88% to 12%. The definition, refined over 14 years of debate, contribution, revision, and honest disagreement, is as follows:

It took 14 years. It was worth every one of them.

The pump deserved a definition that honored it. And now it has one.

I want to thank every single person who contributed to this thread. Every proposal — from PhilosophyOfPump's tripartite ontological framework to KeepItSimple_Dave's beautiful, stubborn insistence that "the pump is the good feeling you get when you lift" — shaped what we arrived at. Every argument mattered. Every debate was necessary.

The pump has been defined. The thread continues, as it always has. But the question has been answered.

I still disagree.

I have disagreed since August 19, 2017, and I disagree today, February 25, 2026. That is nine years of continuous, documented disagreement. I want this on the record.

The definition says the pump is "achieved." The pump is not achieved. The pump is not something you go out and get. You do not achieve the pump. The pump arrives. It comes to you. It descends. It is involuntary. The greatest pumps in history were not planned — they happened. They overtook the pumper. The pumper did not choose them.

The word "achieved" implies agency. It implies control. But the pump is not controlled. The pump controls you. Anyone who has experienced a true, deep pump knows that you do not decide when it begins or when it ends. You are a vessel. The pump fills you and then the pump recedes, and you had very little to do with either event.

I have made this argument 347 times in this thread. I have made it in 6 separate subthreads. I made it at PumpCon 2018, 2019, and 2022. I was not invited to PumpCon 2023 but I made it in the parking lot.

I have a 4,000-word rebuttal saved in a Google Doc. It is titled "Why the 2017 Definition is Wrong: A Comprehensive Analysis of the Involuntary Nature of the Pump." It has been viewed 2,300 times. I will post it again if necessary. I will post it right now if anyone asks. I will post it even if nobody asks.

The vote was 88% to 12%. I am the 12%. I will always be the 12%. The pump does not arrive by consensus. And neither does the truth.
