Himalayan Hotpot
When you are forced to use a toilet cubicle that has been previously used by a chain of people. The effect is a heated seat and repulsive combined odor. It frequently occurs in high traffic places like work toilets at 9am just after everyone has arrived. Or at the airport...which is also known as a Heathrow Hotpot.
God damn, just got caught up on a Himalayan Hotpot in the gents. I'm over this shit!
