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.
The hidden line in
the song "i will do anything for love".

.......
"
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?"
