The act of defecating in the upper tank of the toilet. Much like an upper decker, the texas tanker must be hard and cannot be the liquidy product of a long night of taco bell and misery. When the Texas Tanker sets sail, it can float without sinking giving off a horrid smell for days. The texas tanker should only be used on people who have wronged you in some way.
My boss really pisses me off, if we go to his house for a party ill have to let a texas tanker make a port call in his master bathroom.
