You need to chill with this "Special Weeb Booze" crap, you just didn't know that Sake was a alcoholic drink; and you not liking alcohol doesn't make better than anyone else.

I'm pretty sure the image is referring to sake (sa-ki), a Japanese alcoholic beverage, and not the word sake (sa-k). Basically following the old "pirates and rum" connection but adding a Japanese flavour due to One Piece being an anime.
