this rare specimen (only two reported usages in the wild) means to convene together to agree on a plan of action; evokes the practice of a huddling sports team forming a circle, with each member placing one hand in the center, as it prepares for an important game or decides on a specific play; the leader or captain’s hand is usually the first in the stack, with all others placed on top of it one-by-one; in this manner each person signals their alignment with and commitment to the agreed approach; this phrase may be followed by the object of discussion, as in: “Let’s stack our hands around the new Middle East strategy”
