Coolant spraying... What is going on?

And you are correct, not all of the coolant went back in. Dumb ass mistake on my part, I should have figured this out by myself. But, that is how we learn and the reason for this site. ;-)

I have even seen where repair shops make that mistake and kill someones engine.

Worse case scenario, you can drive it somewhere if need be with the cap loose + a rag zip-tied over the neck to hold cap in place after it pukes out some coolant and the system settles. That is, as long as it shows a few inches or more above the bottom of the bottle.
