Jarring means collecting your bodily waste and/or fluids (generally describing urine or feces, but also includes sperm, blood, phlegm, pubic hair, boogers/snot, earwax, puss, those little
tails that come from blackheads, fingernails, and nut-butter) in a small jar. Commonly practiced
by psychopaths and the extremely lazy. The lazy hide their jarring from others (usually under their bed) and psychopaths jar for many years
and display their collection(s) proudly on shelves.
