An act performed by a prostitute or hooker, typically for a very high price. The lady or gentleman of the night will place you in the driver's seat of your car, encase you in whiskey-flavored jello-o, and lock you inside. Typical rates for a Nashville Bathtub generally run anywhere from $200-$1,000, depending on the size of your vehicle and the professional caliber of your companion.
My wife left me because she could smell the evidence of the Nashville Bathtub I did in her Altima.
