A large quantity or amount of something, used informally when you have way more than you need.
Possibly from German 'Oodles' or perhaps an alteration of 'oddles.' The origin is uncertain, but it emerged in American English around the late 1800s as informal/colloquial slang.
Nobody's quite sure where 'oodles' came from, but it perfectly captures informal American English—it sounds fun and silly because it is! The fact that we don't have a definite origin makes it like language archaeology; sometimes the best words just appear without documentation.
