If you're in the US, how can you not be? It's everywhere! The fledgling US was desperately in need of authority and gravitas, so they essentially cosplayed as the inheritors of the ideals of Rome, and put that shit everywhere.
Why does Washington DC look the way it does? Why are there pillars and obelisks and domes and white marble everywhere? Why is there Latin on the money? Why does every US courthouse look like a Roman temple, and why is there a Roman goddess on it?
The trend is popular because it's laughing at men for being "nerdy", but I think it's sad how ignorant a lot of people in the US are for not knowing about or recognizing the absolutely enormous amounts of references to Rome that exists in modern US.
