A young male who is acting in a mindless and foolish manner and in so doing either creates or threatens some havoc or destruction. Early exhibitions of machismo, but in some silly fashion. My northern Italian grandmother explained it to me that the mamalukes were young Turkish warriors raised from infancy to be warriors who blindly followed orders - the cannon fodder.
Five year old Stevie knocked the pie off the counter and upset the chair while chasing his sister and roaring like a lion. What a mamaluke!
