Basically a Christian masturbating (inspired by another masturbation phrase called 'Greasing the Monkey').

Where one person gets chastised, but others are also admonished simply by being in close proximity - similar to splattering grease.

The shit smear left on the back of the toilet seat. Commonly caused by explosive diarrhea or incorrectly positioning your asshole.

Grease monkey” is a flirtatious, confident, and sometimes cheeky term for wet kitty (i.e. female genitalia, especially when aroused). It’s often used with a little attitude and swagger—implying ownership, desirability, or exclusivity. It can also represent something deeply personal or untouchable, like a prized possession.
"This grease monkey got him acting like he in love."
"Nah, he fumbled. This grease monkey on lockdown now."
