A joint that is comprised of the roaches of other joints. Makes for superb smokage. The roach that comes from the "roach joint" itself is a "grandfather roach", a bit of weed that has somehow survived two joints. Hence, a "grandfather joint" is in turn a joint rolled, comprised of grandfather roaches, and just a delight to smoke with your buddies.
