A sugar mommy is a wealthy woman who financially supports a younger partner through an allowance, gifts or expenses, in an openly agreed arrangement. She is the female sugar daddy. Sugar momma, mama and mummy mean the same.
Sugar mommy, sugar momma, sugar mama, sugar mummy: which one is right?
All of them. They are the same word, they mean the same thing, and no dictionary distinguishes between them. Look up the sugar mama meaning and the sugar mommy definition side by side and you get the same sentence twice.
The only real difference is regional. Momma and mommy are the American spellings. Mummy is the British-English form. Sugar mama is the version most reference works list as the main entry, which is why a sugar mama definition is the easiest one to find. Sugar mom is a shortened form, and the sugar mom meaning is identical again.
If you were wondering whether you had it wrong, you didn't. Nobody agrees, including the dictionaries.
Where the word comes from
It was named after "sugar daddy", not the other way round.
Merriam-Webster gives the etymology of sugar mama as, literally, "after sugar daddy." The Online Etymology Dictionary dates sugar daddy to 1926, built from old slang where "sugar" meant money and "daddy" was a familiar term for an older man.
The two dictionaries disagree about when the female version appeared. Merriam-Webster gives a first known use of 1926, the same year as the male term. Dictionary.com dates it to 1965–70. That is a forty-year gap between two reference works of equal standing, and neither explains the discrepancy. The answer is less settled than a single dictionary lookup suggests.
The derivation is more than a piece of trivia. A word that exists as a variation on another word carries the assumption underneath it: that the arrangement's default participant is a man, and a woman doing the same thing is the special case needing its own label. That assumption is why people are still surprised the arrangement runs in this direction at all, and it is a century old.
What a sugar momma actually is
People asking what are sugar mommas usually want more than a one-line gloss. The dictionaries are right about the core of it, and worth quoting rather than paraphrasing. Merriam-Webster: "a wealthy woman who gives financial support to a typically younger lover." Dictionary.com: "a wealthy woman who spends freely on a younger person, generally a man, in return for companionship or sexual intimacy."
What none of them tells you is how one actually works: what gets agreed, how the money is handled, what people expect of each other. That is covered properly here, because it does not fit in a definition.
One thing worth knowing before you go looking. Real sugar mommas exist, but the message that arrives out of nowhere offering you an allowance is almost never one of them. If someone contacts you first, unprompted, and there is money in the first few messages, that specific pattern is covered here.
