The original meaning was literally when a man uses his penis to stimulate a woman’s G-spot during sex which causes intense orgasmic muscle contractions leading to the woman involuntary defecating. The sentence was a boast as to the prowess of one’s sexual ability and had less of impact if the said woman had pre-existing fecal incontinence problems. Often used by over 65 adults due to the age in which it was first used.

As the term became more widespread, it started to mean simply having intense sex without the any defecation involved.
ex1: “Ethel got it good last week. I fucked the shit out of her. She never had it like that before and was thankful for the rubber sheets on my bed.”

ex2: “I wasn’t really into Mortimer. When I finally slept with him, he fucked the shit out of me. I felt so mortified and he kept laughing and pumping harder as it came out. It felt good but far too shameful. So… no, I won’t be seeing him again.”
