Squirrels are known to have a large testicle-to-body-ratio, i.e. they have lage lesticles in relation to the body. During mating season, male squirrels fight for females and territory. During such fights, the male squirrel tucks away his testicles into a furry pouch in order to protect them. Sometimes, however, a male is suprised by a rival and must fight quickly, leaving no time to tuck away the testicles. Consequently, the squirrel has to fight "balls out," a term that has come to refer to heated, all-out confrontations in the human world.
Wow, that squirrel there snuck up on the other one and made him fight balls out. Guess that settles that procreation conflict for the next few weeks.

This is a serious condition that effects many athletes, it occurs when a sprinter wears very short shorts and then sprints. What happens is his nuts flap outside the shorts and are clearly visible to all. It is disgusting and must be prevented at all costs.
When Calin jumped long jump he always went balls out and never wore spandex underneath his shorts, hey it pays to advertise.
