A contraction of
congratulations and fuck you.
A very specific version of dying inside.
It's a means, look, or an overwhelming feeling to
congratulate someone's good fortune often at the cost of your misfortune. I.e. to
congratulate something outwardly while internally thinking FUCK YOU!!!

delirium of confuckulations.
