Banzai is a Japanese word almost same meaning with English word "Long live the king!!".
Direct translation is "10000 years!". Thus, it can be applied not only to emperors but to anybody anything.

The word was invented about a hundred years ago in the period of Meiji emperor era, the era when Japan opened to the world and rapidly modernized and defeated China and Russia at wars.
Ever since the word is commonly used by Japanese peopele when some good fortune occured to them in private life to official matters. Nowadays the word is nothing to do with emperors.

To Americans, banzai became familiar with the scenes of Japanese soldiers shouting when they won battles or when they committed suicidal and kamikaze attakcs. As old Japanese society never allowed Japanese to surrender, they had no choices but die, and the last moment they shout "banzai".
When somebody marry, people would shout "Banzai".
When accepted by a great University, a student would say "Banzai".

1. A tactic utilized by the Japanese Samurai and later the Imperial Japanese Army from the feudal era up to the end of World War 2.

Where when the enemy has weakened their unit to the point where it has no option but to retreat or surrender, they issue a "Banzai" charge in which they rush head first into the enemy and attempt to engage in close combat, usually with bayonets and swords.

Typically an act of self sacrifice rather then to dishonor their army and country by surrendering to the enemy, an action related to Bushido.

It is traditional to scream the word before attacking followed by a non-linguistic war cry.

2. Slang in video games for a hopeless rush against the enemy, often without any Japanese or Bushido affiliation.
1. "We've got both flanks locked, they gotta retreat sooner or later!"
"Banzai!! AHHHHH!!!"
"Shit, banzai charge! Fire at will!"

2. Damn man you banzai'd bad on that one.
