Break the pencil is a sexual game where one member (usually male) has an erection and balances on it. The male, or the pencil, is usually suspended in the air with the tip of his dick touching the floor. Then one by one women will sit on the man's back until the suspension system breaks, causing the man to fall with his dick snapping in two like a pencil.
