How inauthentic. If you don't remember someone's name, just say so. Ask them again and try harder next time. If I see you with glasses on, and your eyeballs looking above my head I'm going to walk away from you.
The simple solution is that you live with the small amount of awkwardness this generates.
And if all fails, a "What up DUDE!" always works well too.
Now if you have a brain issue or something, I understand. But as a normal, healthy person, if we aren't making even the smallest effort to remember names, even the non-important ones, then we are more than likely the problem hah!
