fistula 

a fistula is any type of necrotic hole from one thing to another on the body. Like a bladder to anal fistula, or vaginal to anal. Each more disgusting than the last.

Jesus, that guy had a fistula so bad, that whenever he tried to have sex, he shat out his dick.

Fistula 

Dracula's gay brother. You know, the one that enters your room late at night with a bottle of lube and that cheeky grin that says, 'That's right. I'm all about the ass.'

rectovaginal fistula 

A rectovaginal fistula is a medical condition where there is a fistula or abnormal connection between the rectum and the vagina. Rectovaginal fistula may be extremely debilitating. If the opening between the rectum and vagina is wide it will allow both flatulence and feces to escape through the vagina, leading to fecal incontinence. There is an association with recurrent urinary and vaginal infections.

Funniest disease ever!!!

Mike: "I was fucking this girl the other night, when all of a sudden, she just shat out her vagina! It was horrible! I Donkey Punched her and left...
Stu: "Well Mike, what you got yourself there, is a classic case of the ol' rectovaginal fistula".

Rita's recto-vaginal fistula made my cock pop out of her ass while I was pounding her pussy.

Thomas didn't believe Britney had a recto-vaginal fistula, so she squeezed out a series of quarts and cooch turds to convince him.
