What defines a "slab" in your area of the world ?

[Ketchn]

With the introduction of electronics that help folks seek out the really big crappie, has it changed the definition of a "slab" in your part of the world ?
"regular" joe folks here call about anything in the 12 inch long and up range a "slab" at most spots I frequent.
And in some cases it isn't just about the length of the fish in my opinion. H managed to ketch a blackie the other day that was a bit over 14 inches long , but it had shoulders and girth and was extra heavy . It was for sure a "slab" in these parts , but in other parts of the world maybe not so much.
So let's hear what is considered a "slab" in your areas, and yes I know it is highly variable and some places grow really huge fish, but other places not so much. In some spots I visit a "slab" might be a 12 inch fish and other places it might be a 15 inch fish.
Please keep it friendly ya"ll , not every spot is a Grenada , just saying
