The other definitions of this word are also right, but the word banzai is used as a symbol of cheer. Banzai basically means "hands up" but in a cheerful way. When you put your hands up and say banzai, it's more of a "YAAAAAYYY" than a "hands up".

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

When Japan entered World War II, the KamiKaze pilots and foot soldiers were told to scream BANZAI!!! just before their deaths as a salute to the emporer.

In reality, very few people did this, and just screamed for their mother, the same as all soldiers did.
