lol, I code alot and don't understand half the gibberish most programmers write.
And I have a masters in compiler design and construction...
if your not in the room working on that little chunk of flotsom, why the hell would you know what they are talking about....
It's not you, it's gibberish...lol...
I just realize awhile back because I was doing it all the time:
"It's actually a cry for help because they are lonely working alone and need to vent..."
They need to get more self actualized (to many of them don't ind this out till they are to late in life)...
So, I find it best to say, boy that's interesting smile 
and change the subject to women, sports, poker, music, family or food... 
Or if you want a blank face Politics or Religion....
Just by 2 cents...
A pity my upvote is under 2c so you get nothing, for I enjoyed reading your comment.
When I was much younger, I had a Sinclair Spectrum and I learnt to use Superbasic and make little programs and games. Does that mean I am entitled to call myself a programmer?
