What do you define as a "Slab"

Not the fella , the fish .....
I realize the definition of "slab" "hog" "donkey" "barndoor" "horse" and or even "whale" will vary greatly from water to water and state to state , but in the end ....
let's hear your definition of what is big enough to qualify the use of said term or terms to describe your larger crappie ....
This black crappie and white crappie fall into what I would define as larger than average specimens in these parts ....
and could possibly fall into the "slab" category ....
now quit fooling around and show us them fish you call big ....
