a Bouncer is a damn-near indestructible mug manufactured by Rubbermaid
. it sports classic good looks and a spiffy handle, and has the advantage of resistance to everything
empirical evidence has shown that Bouncers can withstand >300ft. vertical drops onto concrete; sustained temperatures lower than 77K (-195.8degC, the boiling point of liquid nitrogen) and higher than 400degF (200degC); exposure to xylene, toluene, isopropanol, acetone, mineral spirits, and other solvents; and magnetic pulses from a 9ft. Tesla coil.
the only way i've heard of a Bouncer being reliably broken is by propelling it by means of a linear potato accelerator into the side of a dumpster at 12ft or less.
in that case, fucking duck and wear a helmet or something because you're going to die otherwise.
