おっぱいのペラペラソース
A Japanese meme that originated from a mishearing of "¡Os voy a romper a pedazos!" ("I'm gonna rip you to pieces!"), a Spanish-language enemy voice line in the original [i][[Resident Evil 4]][/i] (the 2023 remake has a slightly different wording for this particular line).

The Japanese-language [[mondegreen]] has several different translations, most commonly to the effect of either "flimsy boob sauce" or "blah-blah sauce on my tits".
