The rehehehe clip spread as a short meme sound on soundboards and TikTok edits, where creators reuse the same giggle for pranks, fails and reaction jokes.

It sits alongside other laugh clips and goofy ahh sounds that editors swap in for cartoon reactions. Because it is only a second long, it fits tight cuts and loops cleanly without covering dialogue.
