A really random saying that originated from public schools in Jersey City in the mid 2010s, used when somebody is getting grilled or embarrassed, especially if you really want to annoy them.
It is used in the same way as "gotteem!" or "ah you mad", and it references the Hump Day Geico commercial specifically when the camel is like "Mike Mike Mike Mike Mike what day is it Mike?"
