Ahh PG,
Snootily continuing in your role as the stick-in-the-mud, I see. 
The “riffraff vibe” here was more in the absence of wearing designer clothes along with our retorts to some reactions when they found out we didn’t attend one of the tony tri-state area private/boarding schools and shudder attended a NYC public school.
Retorts had some overlap with jokes alums from my and older HS graduating classes had about Princeton and its students/alums. Figures considering you’ve mentioned how much you admired Princeton in previous posts.
