The beard stubble guys with weak facial hair grow when they only shave on the weekends. Like 5 o'clock shadow, except it takes all week to grow.
Guy 1: Dude, you got 5 o'clock shadow.
Guy 2: I know, I haven't shaved since Sunday.
Guy 1: Dude, it's Friday. That's Friday shadow.
Guy 2: I know, I haven't shaved since Sunday.
Guy 1: Dude, it's Friday. That's Friday shadow.

Person 1: Hey, just checking if you’re doing alright health wise? I’ve noticed that you haven’t been as regular on your bathroom trips this week.

The Friday after Thanksgiving when ignorant Americans stand in line for 13 hours and stampede over innocent bystanders in order to get a deal they could've gotten 3 weeks ago on that George Foreman grill if they would have used that fucking coupon. As a retail employee, this is THE WORST day of the year.

Day before a day off in the middle of a work week. The term “fake Friday” is used because Friday is the day before the weekend, so “fake Friday” is the day before a day off that typically wouldn’t be regularly scheduled. Fake Friday can often be compared to Christmas because of how exciting is it.
