Resembling, containing, or having the nature of blubber; thick, fatty, or pendulous in appearance.
From blubber (whale fat, from Old Norse blubra) plus the adjective suffix -ous (from Latin -osus, meaning 'full of'). Describes something that has blubber-like qualities.
The word 'blubberous' is rarely used because it's genuinely insulting—calling something or someone blubberous means lumpy and fat, which is why most English speakers avoid it despite its perfectly logical formation!
