Although the definition of the balls on the forehead and penis down the bridge of the nose is accurate, what is not accurate is the genesis of the term. Astute observes might notice that ancient roman war helmets did not in fact have a nose piece.

The reason that it is called a Roman Helmet is that during Caesar's conquest of Gaul, he had their leader Vercingetorix surrounded in Alesia when the Gallic reinforcements arrived and surrounded the Romans. Outnumbered and demoralized, Caesar rallied his troops by offering a soldier who had lost his helmet his balls and penis as a replacement. So moved were the troops at Caesar's offer of self-sacrifice that they went on a rampage and defeated the Gauls. The rest is history.

A variation of the "Roman Helmet". The act of a man laying his testicles in someone else's eye sockets and laying his dick down the middle of the persons nose to their lips making it look like a Roman Helmet. The man wears a condom thus making it a "Trojan Helmet"
I want to be "protected" so I think I'll do the "Trojan Helmet" on Billy instead of the regular "Roman Helmet".
