A slang term for a human female with enormous natural breasts, bigger than tits, boobs or melons. So named because without a bra they hang to the girl's chest. Most common on lactating MILFs, however some younger women with macromastia/gigantomastia can also sport a pair of these. The easy way to tell is push them up when the girl is laying down - if they comfortably fit under her chin or can cover her face then you've got a pair of udders on your hands.
Melanie's udders were so huge that when she laid down in bed and pushed them up she was in danger of suffocating.

The huge mammary glands of a cow. On four legged cows udders have four teats. On two legged cows udders have two teats (or in the case of the two-legged variety the teats are more often called nipples).
The farmer felt kind of embarrassed the first time he touched the cow's udder to get milk, but as soon as he got used to it, he would go so far as to pull his baby daughter off the udder to get some of his own.
