A moron who is full of shit. Usually someone who professes to be an expert at everything, but in reality 1) knows very little, 2) has completely incorrect information, or 3) knows of nothing of interest to others (drivel). However, regardless of their lack of knowledge or of pertinent information, they feel compelled to talk ad nauseam about their selected topics. They usually find themselves to be an expert at just about everything.

another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
