When the female does a handstand and spreads her pussy. the male then shits in her pussy and bangs it down with his cock, railing her like a drill. the female then queefs the crushed and wet shit out, causing it to spray the room. the oil refers to the shit erupting out of the female.
"Brandon preformed a Shrewsbury Oil Drill on Chloe the other day, she had scat in her fanny for 2 days!"
