Verb; The act of fucking an aborted or stillborn fetus. To rip open a womens pregnant belly and rip the stupid fucking fetus out and ram your fat cock in its' soft gushy brains until you unload your jizz into its' mangled skull.
The dirty man chainsawed Marys' engorged belly open and pumped her unborn child full of his hot creamy cum. Isn't that cool Greg?

Get the Fetus Fucking mug.
While a woman is excreting a new born through her vaginal wall a man will thrust his genitalia into the soft skull of the new born just as it crowns. The man will continue his thrusting until he reaches his highest of ecstasy. he will then release his proto children into the chasm of what is left of the child’s cranium, all while every party member involved are releasing their rectal waste (including the camera-man). In order to perform properly the infant must not be allowed to fully leave the vajayjay until the very end.
