When one needs to release a colon cannonball i.e. take a huge shit, one will often state that he or she needs to take a tub. It is often confused with the country bumpkin way of "taking a bath", but everyone knows that its about blowing mud out one's asshole.
"I caught Nick 'taking a tub' last night and the stench almost made me pass out where I stood"
