The other phrases (like rave or game) is fun because it represent a dream as in wishing one could only do that. "Eat, sleep, code, repeat" is very much something you can do while working at Google or any other tech company. In fact you might even be, essentially, forced to do it during "crunch mode". It's not a dream, it's a nightmare.

I get that some marketing person thought it would be funny, but work/life balance is and should be a serious subject for developers. This is "real life shit" that decides what relationships you have with your friends, family and colleagues, where you end up living in the future, if you have kids, keep your health, are happy, don't die alone etc.
