The frequent, very solid, and sometimes painful poops which result from eating protein bars and/or protein drinks. This typically occurs from eating too many protein bars or powder, as the body cannot metabolize the supplement efficiently.

When taking too much protein:
These poops usually occur many times per day, stink very bad to the point of potentially killing small pets, can be very painful and solid, and can potentially damage your toilet.

Protein poops are usually accompanied by protein farts, and when combined together, will ensure that the individual does not receive any attention from the babes / hunks they were attempting to impress.

Can result in: loss of girlfriend, loss of cat, injury to most dogs, damage to toilet, and damage to ass.
