[Ads-l] sentence-final "so"

[Jonathan Lighter]

I've been noticing this for possibly five years, but it could be more or
less.

Quora.com:

Q: Which is worse, homophobia or cacophobia?

A: I mean, more people are homophobic than cacophobic so.

I'd have put in a comma before "so," because there's usually a pause.

It seems to have developed from a feeling that more should be said, but the
speaker doesn't know what.

My feeling is that it was preceded by the (still existing), "so -- you
know."
