Fermentation had to be actively managed because it was so intense. The airlock popped off twice and hit the ceiling (can see where). So I had to try to sanitize the mouth of the carboy with a paper towel soaked in starsan and replace the te-sanitized airlock. The airlock dried up and had to be refilled too. During these things I suppose I could have contaminated it. Airlock popped off and only when I went to check on (several times a day) it did I discover the exposed carboy mouth.
That's likely where you picked it up. Any infection had to happen during the ferment, the bucket wouldn't be enough time to cause the off flavors you mentioned to develop. While over priming can cause gushers, you noted it's sour, so sounds like you indeed have an infection. My guess is that it was infected when the airlock popped. Try using a blow off tube (1" dia tube) during the initial vigorous ferment, then replacing with airlock once it's slowed. I'm thinking the infection was there, but may not have been initially noticeable in terms of aroma until it had been agitated going into the bottling bucket, perhaps warmed a bit too...
