Bit of an in joke in our work office between helpdesk members. Nice solution to some problems.

KFB
Stands for Ka-friggin Boom!! A term used in the gasoline, chemical or fire safety industries for an explosion or potential explosion that is often easily preventable.
Don't forget to check for fumes before using that saw near that tank or we'll have a KFB on our hands.
