Of a grotesque or absurdly exaggerated giant-like quality; grotesquely enormous.
From French 'gigantesque,' combining 'gigant' with the suffix '-esque' (having the quality of, in the manner of). This borrowed French form adds a sense of exaggeration and artistic grotesqueness.
The '-esque' suffix is underused in English—we have picturesque and grotesque, but gigantesque survives mostly in artistic and literary contexts where writers want that theatrical, over-the-top feeling!
