A slut slab is created when you have a king size box spring underneath a queen size matress with no frame. The extra hangover created is the slut slab. Slut slabs come in handy when sluts unfortunately have to sleep over.
"Dude that sluts getting dropped off is she crashing with you"
"Yea but she's sleeping on the slut slab"
"Fuck no, get on yo slab hoe"
