I can't guarantee what I'm going to say is right but I'll give it a shot
when they make the sound twice, it usually is like a sound effect, problem is we usually don't have those sound effects
I did a quick google search and the only thing I could find was this
>>Purin: "Purinpurin shiteiru", which, after doing some research, I can come to the assumption means "to be smooth" (though it's also worth mentioning that "purin" means "pudding").
The guy isn't even really sure himself. I checked jp wikipedia

I don't exactly comprehend it all but um, it can be 3 different things
1-comical combi (I think, which is like baby stories or some crap)
2-event of flushing a toilet in italia
3-NHK puppet show, purinpurin story, with like a princess
If there was some context of where you got purinpurin then that makes answering your question a million times easier, or maybe this already did, I dunno
