A psychotic break or mental breakdown caused by prolonged exposure to a monotonous, unrewarding, tedious, or otherwise mind-numbing workplace, typically (but not necessarily) one considered to be entry-level, or one that pays minimum "wage."
At Walmart this morning, I caught an eyeful of the wage rage, an employee was really waging out; I found them crying and screaming in the bathroom.
Wage Mom is used to describe your femaleboss who cares about you like a mom, but still pays you at the end of the month. It could also be used to ironically make fun of your male boss.
Andrew: "Hey man, wanna meet after work today?"
Bruce: "Sorry man, my wage mom asked me to do overtime."
