The fundamental rules in amateur foosball with the primary focus of trash talking are as follows:
1. Watch out for the stuff
2. Always Win
With the first rule as the focus the awarding of the title of most stuffed man or MSM is if one has a memento of some type, ie. A Championship Belt or perhaps a travel coffee cup. Other acceptable methods are repeating that someone is the MSM or writing it on a dry erase board.

Once said methods have been applied the title cannot be refuted or transferred.
