When the owner, moderator, or administrator of a place must ban someone. Instead of saying ban they formed the bananana hammer from raging on their keyboards.

Imagine someone was griefing on a minecraft server, then the moderators would "banana hammer him". If griefing was against the rules in so said server.
Joh:SuperCoolked99, You were griefing!
Gunney: Banana him!
LowLife: No! let me banana him!
Domz: Banana him!!! LOLOL
SuperCoolked99: No please! Not the banana hammer! I won't do it again!
Joh: HERE COMES THE BANANA HAMMMMMMMMMMMMMMER!!
