When a man pours a large amount of lube on his penis and in the asshole of his sexual partner in order to assure a well lubricated fit. After the male is finished with the intercourse, and pulls his penis from the other person and the other person shits creating a liquid that is a mix of shit and lube. This liquid looks similar to crude oil so the word is "Striking Oil"

When the “crush” has no intentions of taking things further, but they like the attention. So they flirt here or there, send dm/texts just to keep the person interested, knowing damn well they’re staying single.

When you are having anal sex and the bottom didn't douche correctly and you end up with shit on your dick.

when you bring on a period through intercourse with a woman.

The definition of striking oil is when the dirty bitch go's on all fours and spreads her ass hole open and squirts a hell of a lot of lube up that ass. Then the horny mother fucker approaches the lubed up ass hole and plow that bitches hole until she makes a ummpphh sound and a whole lot of brown shit and lube squirts out of her ass hole like a fucking hose. Then you punch that bitch in the face and take a hot steamy shit on her face.

A Devious prank done by one male to another. It is done as the victim is sleeping on their back. You get naked from the waist down. Climb over said victim and hover your ass/choad/balls over there face, then smack them in the balls.
