だいごみ [daigomi] – This word refers to the most interesting/pleasurable/thrilling thing in some category.
The word 醍醐 comes from Buddhist traditions and refers to the highest ranking of purified milk. Though the usage is different and broader in Japanese, the idea is similar to how we say “the cream of the crop” in English.
kore zo ningen no daigomi!
“THIS is why it’s great to be a human!”
(exclamation after some really awesome experience)
