When you've eaten so much birthday cake, or just cake, you feel almost wasted. People who are cake wasted are usually in a daze, close to unconsciousness,(or already), and/or swollen with a food baby.
A mix of a "caker"; a word used to describe the young generation of canadian people, Cakers have a bad taste for food, music, fashion and overall lifestyle, and the term for being a useless waste of space and time "wasteman". We combine the two to form the ultimate insult to Canadians, "wastecake"!
