A slang used by a group of friends in a group chat or chat meet where you talk about a lot of degenerate stuff and keep it a secret between each other.
Example 1:
Man 1: Dude i just recently got a Nezuko figurine!
Man 2: Damn dude that's cool. I recently got a Succubi figurine in a bikini.
Man 1: Oh shit dude. Yo, we both have figurines. Wanna have a jar talk sometime?

Example 2:
man 3: Man I am bored.
man 4:Want to have a jar talk then? Just letting our imagination loose.
man 3: Alright man.
