Residue of any bodily fluids, sexual or vital, found remaining on the table after a table time incedent.
In some social groups it is considered an honour to be allowed to dine upon the table scraps. In others it is frowned upon and a damp cloth used to erase any staining.
It is for this reason that most table time incidents now take place over wipe clean surfaces.
"Go clean yo'sef up while I get workin on these scraps"
