I've come across with the phrase below:
I often have a craving that goes something like this: “I want to eat
tacos.”
I searched online dictionaries but I couldn't find any meaning for it.
So could you please tell me what the meaning of "It goes something like this" is?
The full text is:
Every behavior has a surface level craving and a deeper, underlying
motive. I often have a craving that goes something like this: “I want
to eat tacos.” If you were to ask me why I want to eat tacos, I
wouldn’t say, “Because I need food to survive.” But the truth is,
somewhere deep down, I am motivated to eat tacos because I have to eat
to survive. The underlying motive is to obtain food and water even if
my specific craving is for a taco.

Longman defines something like as an approximation:
The phrase can be used quantitatively:
which would mean:
When we use the phrase with the word this, we mean that what follows may not be exact. For example, I might say:
By using “something like this,” I’m admitting that I may not be giving an exact quote, or that I might not be impersonating her mannerisms or voice with 100% accuracy.
In the case you quote:
I would interpret that to mean that the craving is more of a feeling than actual words, but the person is trying to put that feeling into words. Because the person has never heard words when having his craving, he explains it by saying it goes something like this.
A paraphrase might be:
You would use the phrase when you wish you could say something more exact than you’re able to do. That’s why (as another answer mentions) it’s often used with music, because most of us can’t carry an exact tune.
