He didn't say "over" unless you are listening to something different than I have.
He said, "You are stuck on stupid. Hooah."
See above if you don't believe me. Others heard the good General say "Hooah" twice, as emphasis to what he had said.
You are correct. The "Over" is my invention. When I have seen Honore remotely interviewed he often uses the "Over" comm protocol. It is just another aspect of that makes him something very special.
BTW: I am hearing quote on Fox News right now. LOL
