Insanely large object (hybrid of giant and humorous), particularly women or men who take up multiple seats on public transporation
I got on the R train this morning and a gigundous lady tried to squeeze into the seat next to me. Needless to say the non-greased pole and the right side of my body were not happy.
Used in Ann M. Martin's Baby-sitters; Little Sister books where Karen uses Gigundoly as one of her favorite words. It means very as in a gigundoly happy day. Gigundo means big.
A hybrid word of "gigantic" and "undies" used to describe only the largest, narstiest, granny panties on the planet. Typically of a cheap cotton/poly blend in a sad floral design. Usually found at Walmart for 88 cents hanging on those flimsy plastic hangers.
