(akin to Bad Hair Day); When a gal's normally perky breasts don't seem so fresh or vital on a given day.
Poor Carol - at the pub after work on Friday, her always luscious boobs were, as usual, the center of attention and much commented upon (privately), even through her blouse and pantsuit. And now here it is the following Monday afternoon: she's had to skip lunch because of an emergency meeting, she's missed an important deadline, a fight or two with a client and alas, her normally shapely knockers seem so much the less today - slightly frumpy, a tad saggy and OMG ! have they SHRUNK ? She's evidently in the midst of a bad boob(s) day.

National Boob Grab Day is celebrated on November 11th. On that day, every male (with the female’s permission) will grab the female’s boobs. Grabbing titties on that day is a sign of respect. It shows that the man thinks highly of the woman, and enjoys the bouncyness that the woman brings to the table.
I cant believe it! Today is National Boob Grab Day! That means I can grab as many Ta-Tas as I want!
National Boob Grab Day is the only time I get to grab random people’s boobs!
