Sai Lao

a name used to substitute someone's real name so they don't know you are talking about them. It comes from the vietnamese word for diarrhea (lao sai)

Person 1: Dude did you see what Sai Lao did the other day?
Person 2 (Sai Lao): Who's Sai Lao?
Person 3: Yeah man! What a Dumbass!
Person 2: Who?!?

Laosaipocalypse 

Lao sai - "Flowing shit" AKA Diarrhea in Chinese Min Nan Dialect
Apocalypse - An ultimate and doomsday event that leaves everything to waste.

Having uncontrollable bad diarrhea that makes your poop hole feels like the aftermath of an apocalyptic nuclear wasteland

Jimmy ate that week old stale bean burrito under the chair that he had a laosaipocalypse

After that ultra spicy curry meal, Kerpal's laosaipocalypse landed him in Hospital .
