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.
