Having second mortgages on a house. Taking massive loans they can't possibly pay off and buying stuff with it that decreases in value over time such as cars.
American flags everywhere. I traveled throughout Europe and the Caribbean and I usually only saw their flag on government builds and here and there. Where as here in the USA the flag is like Franks Red Hot. We put that s**t on everything. Magnets, churches, cars, condoms, every front porch, and street lamp. #murica
