Rape Defense wank
Over on the UC Davis LJ community, someone makes a post about FemDefence, a device that is shaped like a tampon, only with a spike on the end, intended to cause injury to a rapist's penis should he attempt to attack a woman. (Yes, it is meant to be worn in the vagina).

People start wanking. Fight between ghost_coyote and lycaon25 ensues. My personal favorite moment: the soon-to be classic "I'M SO SAD I'M CRYING DICKS!" illustration.

Pretty small, but I found it amusing.

EDIT: The device is fake (From the website: "The idea for the rape-protection device and the woman behind it have functioned as symbols for the debate on inequality between the sexes and men’s violence against women.") However, it still caused a very tiny wank.
