I was doing some ass math in my head. So let's say a person's waist is 34". Of that 34" I would guess 10" is vertical when sitting, meaning 5" on each hip. That leaves 24", a 12" wide ass approximately, add say another 2" for clothing and that's still only 14". 4 inches to spare for the seat, which seams right. So what is the tipping point on being too fat in terms of waist band length? 40"? 42"? 44"?
Seems like the average dude is between a 32" and 36" waist, maybe even a 38", and they usually fit in comfortably. Even 2 bros with a 36" waist each shouldn't feel crowded IMO.
Any math geniuses able to create an ass formula better than mine?
