Harbaughs.khakis is a stupid meme page on Instagram, don’t follow him. He likes black girls way too much, and his friends often call him a white Uncle Tom. Once he even said he would lick a WNBA player’s ab sweat.
Having a moment in which you celebrate for an exciting win, moment, feeling, etc. that you may have at any moment and you rub someone the wrong way during the celebration.
I had a harbaugh moment when I got two snacks at the vending machine when I payed for one. Then Jerry got pissed because I didn't give him my extra skittles.
