This project is going to be fucking great

Translating modern slang and profanity into Quenya, a language created by J.R.R. Tolkien, can be challenging due to the lack of equivalent terms. However, a literal translation focusing on the sentiment might be: "Ilya mára nauva sina tanwa." This translates to "This project will be very good," as Quenya lacks direct equivalents for modern profanity.
