Comes from the root word "muckled" aka being really really intoxicated.

Muckle-city relates to how people say they were "gone" last night. Well where did you "go" to my friend? After careful research the answer is MUCKLE-CITY.
It is the place your soul goes when you are black out drunk and it can't stand to see what you do to your body when you are blacked out, therefore you've GONE..to muckle-city.
"I bought a one way ticket to muckle-city last night"

translation: i blacked the fuck out last night.
