A completely platonic, heterosexual event whereby two men defecate in the same toilet at the same time. As the bottom member of the stack, it is important to observe a proper tucking technique, lest an embarrassing and unsightly mess ensue. Once a double stack partnership is established, it shall persist for the duration of the bottom member of the stack's terrestrial life. Once the bottom stack member passes, the top member is free to pursue a new partnership, excepting that the new bottom member is related to the previous by marriage. A widowed bottom stack member forfeits their freedom to establish a new partnership.
Brian and Josh were a feared duo. They fit together like a jigsaw puzzle, their bodies working in perfect accord. Their office knew not to fuck with their double stack.
