What is a sibilant ? it is like a plosive sound like 's'? or it's something else ?

See here Sibilant consonant - Wikipedia, the free encyclopedia.

A sibilant is a type of fricative or affricate consonant, made by directing a jet of air through a narrow channel in the vocal tract towards the sharp edge of the teeth.

Interestingly, in the TV show "Chicago Hope" several years ago the character played by Adam Arkin addresses the fact that he speaks with a "sibilant 's'" which some consider to be a slight speech impediment, not unlike a lisp.

If you listen to American radio commentator Sean Hannity sometimes you will pick up on his sibilant 's' as well. If you do a Google search for this phrase you will find some interesting articles.

/s/ is not plosive as far as I know It's fricative.
