According to the Urban Dictionary it means to eat the remains of someone's meal. Not a word I have ever heard or that I envisage  using.

A scourge (from Italian scoriada, from Latin excoriare = "to flay" and corium = "skin") is a whip or lash, especially a multi-thong type used to inflict severe corporal punishment or self-mortification on the back

The typical scourge (Latin: flagrum; Diminutive: flagellum) has several thongs fastened to a handle; c.f. Scottish tawse (usually two or three leather thongs without a separate handle); cat o' nine tails: naval thick-rope knotted-end scourge, the army and civil prison versions usually are leather.[1]

The scourge, or flail, and the crook, are the two symbols of power and domination depicted in the hands of Osiris in Egyptian monuments and they are the unchanging form of the instrument throughout the ages;[1] though, the flail depicted in Egyptian mythology was an agricultural instrument used to thresh wheat, and not for corporal punishment.[citation needed]

The priests of Cybele scourged themselves and others, and such stripes were considered sacred.[2]

From a Biblical quotation, scorpio 'scorpion' is Latin for a Roman flagrum. Hard material was affixed to multiple thongs to give a flesh-tearing 'bite' [1 Kings 12:11: ...My father scourged you with whips; I will scourge you with scorpions]. The name testifies to the pain caused by the arachnid. To its generous Roman application testifies the existence of the Latin words Flagrifer 'carrying a whip' and Flagritriba 'often-lashed slave'.[2]

Scourging was the first step in the traditional Roman punishment for parricide.[citation needed]
