The greatest place on earth. =P Often used to describe a great memory two or more people shared. Could be anything from "hugging" to "tap dancing", depends upon what is enjoyable to you. Most of the time it is used when you wanna tell people you did something fun but it's hard to explain why it was fun and you're too lazy to give all the disney world.
Friend: "Hey man, me and my girlfriend went to Disney world last night:)"
Man: "I thought you said you watched tv and ate popcorn?"
Friend: "We did, but I enjoyed it more than normal cause I had her there with me."
Man: "I see"
