look up any word, like bukkake:
 
1.
The sexual act of having sex with a woman during the process of having an abortion induced by an RU486 pill. Right before the man ejaculates he smears the blood and baby bits on the face of the woman and proceeds the wash off the blood and fetus residue by urinating on the woman.
(1) I thought there were no new sex acts, but then when my girlfriend was aborting my child I found a way to combine incest, necrophilia, pedophilia, child abuse, paraphilia, felacio, and normal sex in to a new sex act called the fetal piss.

(2) The fetal piss is the new standard for degrading women.

(3) She's slut, she would probably do a fetal piss if she got knocked up.
