I feel like Maney and Roy would do this.
Looking for a way to supercharge your morning routine? Into conserving water? Okay with some minty foam possibly hitting your bare feet? You’re in luck! Brushing your teeth while showering is an option and it’s not as gross as the naysayers out there might have you believe.
You may be thinking ‘but what if I get dirty armpit water on my toothbrush while I’m in there?’ Which of course begs the follow-up question: what the hell are you doing in the shower? If there is a risk at all, it’s that you might just fall in love with the combo and never go back to brushing your teeth without water splashing in your face again. Meanwhile, the rewards are saving H2O, some time, and no longer having to smell your stanky breath in there.
If you’ve never attempted the shower-brush technique, here’s how it’s done. While the shower is heating up, squeeze some toothpaste on your brush, and give your mouth a quick glance on the mirror to see if there is anything that needs some extra attention. Start brushing, enter the shower, and go to town on your teeth. When you’re done, rinse out your mouth and spit down the drain, then rinse your brush and set it aside (preferably out of the shower). You’ve now entered the elite class of shower-brushers. Bask in your glory.
Not sure I can get down with this, but I get it is socially acceptable now.
