Where does they saying "they call me Roy" come from?

Question

I've saw this several times and wondering what it means

Answer 1

Haven't been able to come up with any documentation.  The only time I recall hearing it is a racial situation.  A white man said to a black man, "Come here boy".  The black man took offense at the slur, & replied, "Did I hear you say, 'Come here Roy?'   They call me Roy, not boy."
