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.

A certain type of prank call chanted in a Japanese accent .
You phone up the person in question with an unknown number
they answer: ''Hello?''
You and 2 or more friends: ''BANZAI BANZAI BANZAI''
Shout this repeatedly until phone call ends. Whispering also works well.
You can also use the word in normal sentences

"Harry is choking on his wand!"

"Banzai!"


-Why Harry P. is putting his wand in his mouth? Who knows. Why a crazy Japanese boy is there saying hurray? Pure crazyness.-

A Japanese show previously shown on the FOX network. It was a gmae show which utilized viewer participation by using text messageable answers. The show involved certain stunts with multiple choice results including how many ballons would make a chicken fly, which carjacker will steal a car first, and which of these women is really a man. The show was short lived, but still attracted its loyal viewers.
Banzai was a very funny program on FOX.

An idiot; the kind of person who puts a wet knife into a powerpoint and turns it on.
That banzai sure is dumb.
