Geriballz 

Testicles of a male over 60. For reasons unknown, they are often prominently displayed while walking about men’s locker rooms. Generally saggy and more than a touch of gray.

The geriballz were flopping in the locker room today.

The old guy next to me had his geriballz hanging out of his shorts.

gerbilling 

Having a live rodent or small animal (usually a gerbil) and using some sort of tube, forcing the gerbil into ones asshole. No medical case has ever been recorded of someone needing to remove a gerbilfrom ones anus, so we must now come to the conclusiion that either
a) gerbilling doesnt exsist.
B) they are very good at getting the thing out afterwards.
Gerbilling has many famous cases, such as richard gere reportedly having a wild session with the furry animal.
For more information i recommend the south park episode "Death camp of tolerance" which features rather detailed examples of gerbilling.

"Im bored, what should we do tonight?"
"I dunno, how about you shove that gerbil up my ass, wait for it to wrigle around and maybe die, then you can pull it out."
"So whats on TV again?"

gerbilling 

(vb) An imagined act, (obviously homophobic in origin) in which people (presumably gay men) engage in sexual thrills by inserting a live de-clawed gerbil into the anus of the other person (by the means of a tube). Urban legend asserts the frantic movement of the poor furry creature trying to escape causes sexual stimulation. Although the rumors of this practice have been around since the early 1980s, with thousands of Google references to this, not one documented case of the practice exists. Reference to "gerbilling" is nearly always done with knowledge that the tale is false; it is simply a malicious and hostile disparagement of gay people.

Out of all the internet references swearing to the veracity of gerbilling, it is telling that in almost instances, purveyors of the rumors are

>>>anonymous<<<

Anonoynmous peddling of trashy rumors meant to disparage is really chickenshit. It is about the lowest thing a person can do. (This entry is NOT ANONYNOMOUS -- if you have a problem with it, please feel free to contact me.)
