Eternally Single Woman. Someone who manages to avoid marriage and/or single motherhood, and yet doesn't become a hermit or old maid. Usually takes care of herself like younger single women do. Makes the moms of the world jealous, and 40+ men horny.
When I divorced, it was tough re-joining the singles scene. Logistics with a MILF are difficult, and ESW's are hard to find.
