Why is egg and orange juice such a bad combo? [closed]

Eggs and orange juice are not uncommon around the breakfast table, but unfortunately, eating and drinking both in the same mouthful was an unpleasant surprise.

It was as if a chemical reaction had created a third foul taste that was nothing like the two ingredients. My untrained tongue can only describe it as bitter.

Update 1:

I wonder why the combination doesn't taste like the sum of its parts; this combination specifically.

Update 2:

Use your imagination! Human perception is merely the null hypothesis (obviously uninteresting), so I'm really asking this: Is there something more to it than that? First of all, is this a chemical reaction, or is it not?

Example answers:

• Oh boy, this is a chemical reaction! Eggs contain sulfur, and oranges contain E300 (acid you know) so this becomes sulfuric acid! That's why.
• The acidic solution breaks down the egg much like stomac juice, releasing H₂S, which tastes rotten. That's why.
• The acid + your spit makes instant biodiesel out of the fats in the egg. Beat that!
• Sad to disappoint you, but nothing special is going on with this mixture. Your tongue tricked you.
