No I'm pretty sure that's right

It's from a meme, "Money printer go brrrr" ~~which was I think a spin off of the "It prints money!" meme for the original Wii~~ (Edit: did some research and I think they're unrelated.) Its the sound of the machine, printing money, it go brrr.

I've seen it used for all kinds of things, but "go brrr" is basically a dismissive way of talking about how "winning" something is.

Edit: I think Picard Manuever explains it better actually, and while I don't think my usage note is untrue from how I've seen the meme used in evolutions, I'd have to agree that it originally and usually takes the form they described.

It's just the sound of some machine running, but the meme is usually something along the lines of:

"You can't do X, you have to do Y!"

"X goes brrrr"

The humor is in stubbornly doing something in a dumb way.

It's generally finding amusement in something doing what it's supposed to do in a straight forward and effective manner, in contrast with an alternative overly complex method.

Pretty sure it's supposed to be the sound of a machine running. Most popular example I can think of is "haha money printer go brrr".

It can also be a reference to the A-10 close air support fighter, whose main gun is notable for emitting a very loud brrrrrrrt sound.

The US government printed a lot of money after the 2008 financial crisis. Some people criticised this, saying it would devalue the US Dollar. But the government went ahead with the plan, resulting in a meme where critics bring up a lot of arguments and Obama (?) says 'haha money printer go brr'.

It's the sound of the A-10 Warthog's main gun. It became a meme over a couple decades of war. "If brute force isn't working, you're not using enough of it," kind of captures the gleeful power and arrogance.
