So the Oxford English Dictionary added some new words recently. I don't think I've heard of cakeage (I know it as the bland, descriptive "cake cutting fee"), but I use hangry and fast-casual all the time - probably even in the same conversation. I've heard many of the other words or phrases numerous times, without ever stopping to think if they were "official" words yet.
It's interesting to see how language evolves over time. The year 2012 gave us such gems as earworm, a music favorite of mine - and how did we ever converse without referring to our bucket lists or game changers? That year had a lot of negative words about the economy, so I'm glad that now things are (a little) better and we can focus on the important things in life - food.
