....is a "LANG" or LANG session? I have run across this term from postings that offered lang and I'm damn curious so any help would be appreciated.
Thanks, fatpimento

But maybe "LANG" is short for language? As in Russian, Asian, Greek?

It's more useful to know which specific languages she speaks.

might be easier to figure out if you post a link to an ad using it as an example.  

it's slang for a few things but you wouldn't  use them to describe a session.

"Is it a crime? Is it a crime to look at Lange?"
