cake water
Misspelling of the term Cake Eater, probably by someone who can't spell or types too fast not realizing the "w" is next to the "e" on the keyboard, or by someone who's nails are too long thus inhibiting the ability to type. Word used synonymously with christ-on-a croissant or blue slushy.
He is such a Cake Eater (correct). He is such a Cake Water (incorrect).
