Ending Sentences With So

There are some repeated aspects of American slang that really make my crawl skin. There are the ones that have persisted such as using "like" multiple times in a sentence (not as a similie or expressing preference), ending a sentence with "at" unneccessarily (such as "Where are you at?"), and including "you know" without waiting for someone to acknowledge that they in fact know what the other person is speaking about.

The recent addition to this list is ending a sentence with "So....". Some people just don't seem to know how to end a thought. Now they have a clever escape mechanism, which is to just say "so" and lift their hand in the air. For example:

Person1: Did you go see that movie I told you about?
Person2: You know, I was like thinking about it and then Angelo called asking me where I was at. I told him and he was like why don't you come watch the game. So...

I beg you people, can we just end add "there you go" so it is a complete sentence.
