What does ぴろーん mean?


This appears to be some kind of adult slang term, or maybe it's internet
slang, whatever the case may be I can't find a definition in any dictionary.
Is it an onomatopoeia?




It is an onomatopoeia, not the name for an object unless the author/speaker
uses it as such for his own aesthetic purposes but this would be fairly rare.

It describes the way a long object dangles, stretches, lies down, etc. in a
lazy manner. The long object coud actually be anything from linguini to a cat
stretching its body, from hair to stretching cheese, etc.

If OP saw/heard the word in adult content, it would probably be about a male
organ.
