The word "on Geoff" is used to swear on something or someone, once you use this swear you have officially joined the cult.

It is used to clarify that whatever you are saying is 100% true and the person receiving the information can fully trust what you are saying.

If you break a "on Geoff" swear you have ten days to redeem yourself by giving or receiving head (AKA blowjob) if you fail this then both of your parents will be executed and when you die you will go to hell and be raped by a overaged Bill Cosbey for 100 years and then thrown into a never ending pit.

If you go a whole lifetime without breaking a "on Geoff" swear you will be rewarded by the Geoff gods and be taken to a heavenly oasis where all of the girls look like Megan Fox and Kate Upton

WARNING: Breaking an "on Geoff" will result in bad luck for the rest of your family's future generations.
