Chunky yarns (Bulky in the US) are thicker than Aran weight yarns, as the name suggests, and usually knit up on 6mm - 8mm needles. These yarns are sometimes called 12-ply yarn.
Chunkies are great for quick projects, and make great hats, mitts, scarves, Winter sweaters, and fabulous homeware items like cushion covers and blankets.
These yarns have a come a long way since they 80s and now don't have to contain plastic, or be unreasonably heavy.
