look up any word, like donkey punch:
A Tepper is a set of male genitalia that has been gelded, or had the testicles removed. Typically this refers to the process of removing the testicles with a crude device, such as a knife, stapler, rubberband, or piece of rusty metal.
They had used a rusty piece of metal to make him a tepper, so his tepper was rotting off.
