A piece of news that is so amazingly interesting that it is considered "fantastic" and "fascinating" at the same time.
Little brother: "My Pokemon is almost level 100!"

Big brother: "That's fantastinating."

Get the Fantastinating mug.
adj. in a manner common in fantasy fiction or bearing many similarities thereto. This word is used due to the fact that the word which previously held this meaning has shifted away to mean "very good".
The tale was very fantastine despite being set in a perfectly realistic context.
