Narrative:

We experienced a decompression, however, it was not explosive, and the captain dropped the masks. All passenger took oxygen (as well as flight attendants) from oxygen masks. This part went as 'normal' as we are trained for. I do want to point out the attitude and cabin pressure just before the captain dropped the masks was bazaar. The G's were very hard and the aircraft felt as if it were sinking and being pulled to the right at the same time. I don't have firsthand knowledge of what the cause was, only that the crew couldn't pressurize the cabin.
