Blocky is a red building block character from Battle for Dream Island, the animated web series that later continued as BFB and TPOT, known for pranks and a mischievous personality. Clips of his voice are often sped up and repitched by fans for soundboards and edits, creating this higher, squeakier laugh. Fans share it alongside other cartoon reaction laughs like the oh no no no laugh, using it in fan animations, gaming edits, and short meme videos where a character is laughing at someone else's expense.
