It doesn't stand for anything. A slab is a synonym for slut. Reffering to always being on her back like a slab of wood or cement. Popular among the urban population but slowly making its way around.
Did you hear about what stephanie did last night? She gave a birthday blowjob to a random guy then went and fucked her boyfriend. What a slab!
