Avisodomy is the act of a human engaging in sexual activity that involves a bird. Due to the size difference between the species, any act involving penetration is usually fatal to the bird.
R.E.L. Masters, in his book (1962) describes it and other zoosadistic acts under "related perversions" as follows: Some descriptions of this act feature the perpetrator breaking the bird's neck as the moment of orgasm approaches.
