Roach is a term for the "un-smokeable" part of a Joint (the end closes to the lips). The un-smoked piece that remains also resembles a cockroach when seen on the ground (due to oil-stains). A Roach-clip is used SPECIFICALLY where a Crutch/Girrick/Tippy/etc. is absent. In cases where a rolled paper is inserted in one end of a joint, the smoker will have a space for holding the joint - in addition to not getting pieces of plant-material stuck inside the mouth.
