Etymology: "Tiddy" is a slang word for the breast, and its history is short and largely undocumented. The source-verified fact is that it comes from English dialects in which the flapping phenomenon occurs. In that process, a "t" between vowels is pronounced as a quick tap of the tongue, much like the "d" in American English "butter" or "water," so a sound that begins as a hard consonant softens into something closer to "d." That tapping is what links the word to forms like "titty" and its pronunciation-based relatives. Because the sound change happens in everyday speech rather than in writing, the word's spelling has varied, and it has never been an official, standardized term. It belongs to informal, colloquial vocabulary, which is why its path into English is hard to trace through printed sources.
