this is also my experience, i always make the mistake of thinking that people want explanations from first principles when in reality the socially correct explanation is usually first order causes. my SO once asked me why some water bottles go glug glug instead of sploosh when you pour them out and then they made a face at me when i tried to explain what a stress tensor was
the correct answer here was that some water bottles have wider bottlenecks than others
"Why do some water bottles go glug glug instead of sploosh when you pour them out?" to mean "I am telling you in an oblique way that I am frustrated by this particular bottle that I am pouring from because it's going glug glug when others pour smoothly."
In this case it's air getting in the way of the water. There's a vacuum created when water leaves the container, but the water is heavy enough to still fall out. The air displaced by the water is light enough to travel to fill that vacuum, but if the mouth is narrow enough, the water gets in the way until the forces are sufficient for a bubble of air to travel into the container, interrupting the flow until the forces are such that water flows again.

fuck, this never even occurred to me
this is probably the best answer actually
What do you think primarily influences the sound when water is poured from a bottle? Is it the material of the bottle or something else?

Tangential but you might enjoy Richard Feynman's "why" lecture.
