Category 1- The creme de la creme of bollocks. Tight, defuzzed, cleaned with some kind of soap and good sized.
Category 2- Trimmed, wiped with a wet flannel and either slightly large or slightly small. A slight smell of sweat is OK, terrible smell will shunt you down to category 4.
Category 3- Untamed, lynxed to within an inch of their lives, size indistinguishable under the 'fro.
Category 4- Scrotum appears to have space for at least 4 more testicles, overpowering rank scent of stale sweat and ignorant of all hair removal methods.
Category 5- Alien nards. Something weird or horrifying, like an extra one, or ropey veins all over.
