(n.) Woo Girl can also be a derogative term when used in context of single women over 35 who are coquettishly over-excited shouting woo at every moment or conversation they find amusing or titallating which most single women are nonplussed ; or women who use online status to shamelessly write (in adolescent tone) about their woo woo moments, as it validates them. When used to refer to women over 35, conveys they are superficially fun and may be genuinely nice, yet lack depth and possess vapid, lonely personalities who have lived a unfulfilling adult life to date and thereby attempt to act as a newly minted college grad . Unfortunately, they commit TMI in the process and overdo it with the woo wooing . As in the episode from "How I Met Your Mother," woo girls hide the fact they "cry in the shower...are secretly attracted to other women...wonders if they'll be a mom" etc. May be a indirect way of attracting men who are social retards.
