Deep Kimchi 

Kimchi is an extremely hot Korean fermented cabbage. It is something you do not want to find yourself in.
The deeper it is buried in the pottery in the ground while fermenting, the hotter it is.
To find one's self in in deep Kimchi is to find one's self in deep shit.

In Deep Kimchi 

Slang for "In deep trouble" or "In deep shit."

In Korea, people would bury cabbage deep underground in a pot and put a lid over it. They'd keep the cabbage burried until it fermented and turned into Kimchi. When they un-dug it, the Kimchi would smell very foul. Many Korean war vets began to use the expression In Deep Kimchi for when they were in trouble.
