Given your description (and your lofty goal of maikng your family puke ) I had to look this one up. I found this description:
"Bulbophyllum fletcherianum is a spectacular, huge leafed species. Each leaf can grow to 1.8 metre (6 feet) long from a pseudobulb the size of an orange or grapefruit.
A native of the river ravine rock faces of New Guinea, it is allied to the other large species like B. phalaenopsis and B. macrobulbon. This species requires a basket or shallow tray with a rich media that will stay damp but not wet. It will also grow on a large treefern slab with extra water. This may help accommodate the pendulous leaves to display them to best effect. When in active growth, the plant requires maximum water and fertiliser and must always be given warm conditions."
Neat looking bulbo, I must say. Good luck with it!
