“Yes, “what the fuck?” is in the lyrics — specifically in the choruses and refrains of EMF’s “Unbelievable.”
Accurate breakdown (from reliable sources like Genius, AZLyrics, and the official track):
• Intro:
(Oh!)
(What the)
(What the, was that?)
• Chorus / Refrain (repeated multiple times):
You’re unbelievable (what the fuck?)
You’re so unbelievable! (what the fuck?)
It’s unbelievable (what the fuck?)
The sampled vocal chop that sounds like “What the… was that?” comes from Gylan Kain’s spoken-word track “Silly Shit” (not a Black Panther speech, as sometimes mythologized).
In the full mix, especially the choruses, it’s layered and often rendered/transcribed as the full “what the fuck?” exclamation.
That’s why some lyric sites and my earlier response included it explicitly — it’s audible and commonly noted in full transcriptions, even if the intro sample is a bit more chopped/muffled. The song famously snuck “fuck” in ~20 times uncensored on radio back in the day.“
