A professional dumbass is a person who does something stupid so well they aren't able to suffer any consequences.
An example of a professional dumbass:
Alix ran into battle without any weapon, once he released he had no weapon he proposed to the general. He is now a married man.
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."
