A name describing an indescribably sexy man. A guy who, unconsciously, can easily get every female in the room aroused with just a casual glance in their general direction.
Men with this name are usually vertically elongated and proportioned in all the right places.
'Jacks' are always destined for greatness. They can pwn anyone at any game when they set their minds to it, and when it comes to performance in the bedroom, they are rarely classified less than exceptional.
Boys like these are hard to find. And when found, and tamed, turn into sex crazed beasts, bent on completely and totally pleasing their finder to the point of no return. Jack's are loyal creatures, and their finders tend to want to hold on to them, as the pleasure they give is very scarce.

Girl 1: Must be a Jack.
