Cups and bowls

Usually when we measure a girls chest size,
since girls chest is their most valuable asset,
they tend to measure it,
in this case, human invented the cup measure,
like a-cup, b-cup,c-cup .....and so on ..

Man on the other hand ,
belly is one of the most observed body parts for girls ,

so how we measure boy/man belly size ?

based on the logic of cup to measure girls chest,
should we use bowls to measure boys belly ?
I can imagine A-bowl belly will look like this ,


Then it slowly progress to B-bowl belly
as we grow older, our bowls grows ,
and by the time we are old enough to have grandchildren
normal guys maybe will end up having C-bowls or D-bowls size belly
in this pic, is confirm G-bowls size belly

when girls desperately make their cup bigger,
boys do it oppositely ,
