It's a slang phrase, I believe. However, wanting to know something new won't hurt, right? I've seen many people use this phrase, but I still don't get how to use it.
I, first, saw this phrase on Facebook. It was a maths meme. The meme
was about a difficult problem that's unlikely to be solved by hand.
Someone commented Wolfram Alpha goes brrr (I hope I remember the
comment correctly). By the way, Wolfram Alpha is an advanced engine to
compute something related to maths and preferable to use rather than
solving by hand.
So, that's the context. I've done searching for a topic related to this phrase, here. From what I've understood so far, this phrase is used when someone introduces a more effective way to solve a problem. Is that correct?
Suppose, my friend has difficulty peeling an orange by his hands, can
I say:Haha a knife goes brrr
I mean, is this phrase even used in spoken English (very informally)?

"Goes" in this context means "says" or "makes the sound". "Brr" is often used to indicate the sound of a machine working. Like we'll describe a car engine as "going brr". So "something goes brrr" means "something makes a working-machine noise". ("Brr" is also used to describe the sound people make when they are very cold and shivering, but that doesn't fit in this context.)
I'm not aware of this being any sort of stock phrase or idiom. Maybe it's a common phrase in some group or sub-culture, but not in common English usage.
So if I was in a conversation and someone described a better way of doing a job, and someone else said, "I go brr" or some such, I'd take that to mean, "I am working on the problem with this new solution". But it would be a very whimsical and informal way of saying that. Maybe even a bit cryptic: I'd wonder, is that what he means, or does he mean ... something else?
I would definitely not use this in a general conversation. It's a cute turn of phrase, but it's not commonly used or understood, and it is very informal.
