Where does the name of the game "egyptian rat screw" come from?  While
the history of the game itself interests me, I am moreso looking for
hte history of the particular name "egyptian rat screw."

"The gameplay of Egyptian Ratscrew appears to be a combination between
that of Beggar-My-Neighbour... and the concept of slapping for cards
on certain combinations, possibly derived and expanded from the
gameplay of Slapjack. The origins of the name are unknown."
