A weighted little guillotine that exists solely so you stop chewing tape off the roll.

means A small, often weighted desktop device that holds a roll of adhesive tape and has a serrated metal edge for tearing off neat lengths.

from A plain compound of "tape" and "dispenser." "Tape" comes from Old English "tæppe," a strip or band of cloth — long before it meant anything sticky, tape was fabric you tied things with. "Dispenser" traces to Latin "dispensare," "to weigh out or distribute," from "dis-" (apart) plus "pendere" (to weigh) — the same weighing root that gives us "pension" and "pendant." So the name literally promises a thing that weighs out your tape, strip by strip; the desktop gadget itself is a 20th-century arrival, born alongside cellophane adhesive tape.
