Similar to hangy tits, groobs refer to breasts that hang down unnaturally low to one's torso or beyond. Formed by combining the words GRANNY and BOOBS to form GROOBS. Most commonly found among the elder female population, yet not excluded from the more disproportionate youth of today.
Daaaaaaaamn, Barbara's groobs hang so low they look like she got them on a direct mail order from an old folks home.
