Cackl e
One of the screenshots used on Umineko's Steam store page features Beatrice saying "And let me also say this. You are incompetent! *cackle*cackle*cackle*cackle*, hiiihhihihhihihihihihihihihihihi!!". However, there is a line break in the middle of the first "cackle", meaning that it gets split across two lines into "cackl e".[1] Years before Joe ever played Umineko, he looked at the game's Steam store page and saw this image, and as a result started saying "cackle ee".
