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.

In 20th century U.S. slang, "kimchi" was occasionally used in the phrase "in deep kimchi" (particularly by veterans of the Korean War), a euphemism for "in deep trouble" and was used in a number of awkward situations.
Stop right there!! You're in deep kimchi young man!
