There are some products that are just tailor made for people who are dicks. The asshole market is a vast one and there are so many items that could be included.
My choice would have to be AXE body spray. That stuff has always been marketed to be douchebags. Assholes are the only adults who buy it, and kids buy it because they think its cool. I will admit I have a couple of cans of it that I hardly used.
Also, anyone who buys a fart can muffler, you’re probably an asshole if you have one of those.
What is a product than only assholes buy?
