8 definitions by Johnny Panic
A penatration-based sex act so warped and craven that it is "of Pluto", i.e. beyond anal. Although "plutonic" does not refer to any specific act, it could include such acts as ear sex, removing someone's glass eye and having sex with the empty eyesocket, sex with a colostomy stoma, an esophagal stoma, or stab wound.
John and Kim's relationship progressed quickly - on Wednesday they were platonic friends, on Thursday afternoon they were fucking, and by Sunday they started getting into some plutonic shit.
