A person that becomes a douchbag whenever there is a pretty girl around. Typically, it is either a girl being ignorant out of jealousy, or a guy being ignorant trying to impress the vagina.
Examples of people being a Vagina Douch: Carl is typically such a nice guy, but he becomes a complete douch whenever Valerie is around. Hey did you ever notice what a douch Tina can be when a hot girl is hanging out with us?
A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
