A sugar daddy is an older man who provides gifts, allowances and trips to a younger woman or man in exchange for a consensual relationship. This is standard American English slang, pronounced shoog-er dad-ee, and its plural form is "sugar daddies." According to Dictionary.com's Unabridged Dictionary, based on the Random House Unabridged Dictionary, the phrase was first recorded in use between 1915 and 1920 - meaning it is a piece of everyday American vocabulary with more than a century of history, not a recent internet coinage.
Knowing that history is useful, but the practical question most newcomers ask is simpler: how to find a sugar daddy in Indianapolis without wasting evenings on vague small talk. On UrbanSugarMeet, that starts with a verified profile and a stated preference for arrangements where generosity, availability and boundaries are discussed openly, long before a first coffee at Mass Ave or a dinner downtown.
