After digging up a corpse of at least 10 years age, pouring gasoline over the genitals, lighting them on fire, and putting out the fire with a large amount of liquid feces, you engage yourself in rough intercourse with the shit-covered vagina and/or ass, and shoot a huge load inside the totally wrecked 'privates'. You then snort it out with a straw, all while singing 'Sweet Child O'Mine' by Guns N' Roses.
Yo, dude! Cheyenne and I totally video recorded Harmony having a crazy zombiegasm down at the old cemetery! She was crying afterwards she loved it so much!
