Original definition:

Bagsy - the ability to claim that something is so unequivocally.

*this is an elaboration to previous rules and regulations sent out by the bagsy committee.

Bagsy - a registered trademark of the Bagsy Association would like to remind its followers of several rules:

1. Bagsy is applicable globally
2. While the Bagsy Overlord resides in Scotland and Ireland, he does travel to many locations to make sure that the bagsy heritage is being preserved
3. You can bagsy that another bagsy user doesn't have valid bagsies, however this type of "blocking" bagsy is only valid for the maximum of a year (for the few who inquired, it is also valid for a minimum of an evening)
4. Once a year has passed from a "blocking bagsy" bagsy, all bagsies by the blocked are valid again
5. Bagsy interacts with other claiming laws, such as "shot" (U.S. usage) and "touching red" (commonly used in Israel) however "bagsy" is dominant and any bagsy stated will overpower other claiming statements and local laws.

Should you have any questions please contact us - and we will be in contact with you.
"I bagsy your bagsies don't count Andy".
