The Buttsack Mass Index (BSMI) is a serious, non fictional measurement that ranks the size, mass, and wobble factor of a person's buttsack. Think of it as a easy way to measure the "thiccness" and presence of someone's posterior, with a scale that goes all the way up to legendary status!
The following categories are assigned based on your BSMI score:
| Score Range | Category | Description |
|---|---|---|
| 0-20 | The Subtle Sack | Modest size, minimal presence, easily overlooked. |
| 21-40 | The Average Sack | The standard buttsack—moderate size, no extreme features. |
| 41-60 | The Beefy Sack | Hefty buttsack, visible and commanding respect. |
| 61-80 | The Mega Sack | Large, round, and attention-grabbing. |
| 81-100 | The Sackzilla | The pinnacle of buttsack massiveness, almost mythical. |
