I've experienced the same symptoms quite often, although not as frequent since my gallbladder was removed.
Prior to my gallbladder surgery, every time I ate a meal with alot of fat I had the orange, oily, greasy discharge which had a foul odor. My body wasn't digesting the fat I was eating. I had tests run and found that my gallbladder was inflamed and that surgery was recommended. The first time this happened it freaked me out.
Even now I try to stay away from foods with a high fat content to avoid this from happening, but last week I ate a large amount of sunflower seeds over a period of a few days, well my body reacted. I was bloated and constipated for 3 days and then I had terrible diarrhea and the orange, oily droplets and greasy discharge with the foul odor that lasted an entire day.
