To sleep Raw On The Floor - is to rest on the ground, normally indoors on someones bedroom carpet, without any comfort
aids or sleeping apparatus (ie: pillow, blanket, sleeping bag..)
Derived from the time when you slept round a
friends house, but forgot to pack your sleeping
bad. Or go to a houseparty - become so intoxicated and pass out asleep on the kitchen floor (usually curled up in the fetal position)
