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.
