The line comes from Regular Show, the Cartoon Network animated series that ran in the 2010s following Mordecai and Rigby, whose exaggerated reactions made the show a steady source of meme audio. Short outbursts like this one were clipped by fans and passed around on soundboards, where they became shorthand for moments of stunned disbelief. It endures because the phrasing is universal, fitting anything from gaming reveals to real-life surprises, and because the frantic cartoon delivery reads instantly even at just over a second long.

Shocked holy crap it's real line from Cartoon Network's Regular Show. A quick reaction sound for unbelievable reveals, plot twists and real-life moments.
This is a split-second burst of disbelief ripped from Regular Show, delivered in a high, cracking voice that shoots up on the word real. The delivery is pure cartoon panic, loud, breathless and slightly raspy, as if the speaker cannot quite believe what just appeared in front of him. It lands like a jolt, turning a reveal into a punchline and making the audience feel the shock along with the character. Because it is so short and energetic, it works as an instant emphasis hit that sells surprise without needing any setup or explanation.
