Hellibration 

When something (an event, for example) that usually is somewhat of a celebration or a positive social gathering of a chosen few or a large crowd expecting to celebrate an occasion together and it turns out to be a horrible experience like a hellish nightmare, it is called a "hellibration".

Our daughter looked so beautiful for her 16th birthday party until her boyfriend showed up, drunk as a skunk, and turned the whole night into the hellibration of a lifetime.
