The Loopback 

Fisting the ass and vagina at the same time. Derived from internet terminology, plugging into the WAN and LAN at the same time.

My bitch was gettin' fiesty so I gave her The Loopback.

pinging the loopback

When a man uses his own penis to stimulate his asshole for pleasure, creating a self-contained feedback loop of gratification. A term born from the tech metaphor "loopback" (where a signal is sent back to its source), this act symbolizes the ultimate closed circuit of self-pleasure.

In IT parlance, pinging the loopback address 127.0.0.0 (or typically 127.0.0.1, known as localhost) tests your computer's own network connection, confirming the TCP/IP stack is working by sending data to itself, not an external device, useful for developers to test local applications and diagnose basic network issues before needing the internet.

Origin: Named after the infamous loopback.jpg shock image, which captures the raw, unfiltered moment of a man inserting his penis into his own anus. The term gained traction as a cheeky way to describe the intense, private thrill of solo masturbation.

Examples:
"She’s so into it, she’s already pinging the loopback by the third round."
"The loopback.jpg is the ultimate flex—pinging the loopback is the ultimate flex -- literally in dick flexibility"

Related Terms: Self-pleasure, closed circuit, loopback.jpg, orgasmic feedback loop.

Note: A blend of technical jargon and primal joy, pinging the loopback is both a literal and metaphorical act—proof that sometimes the best circuits are self-made.

After a long day, pinging the loopback was just what he needed. With a little KY, some flexibility, and patience, he would soon jizz in his own asshole and reset his soul.

Agouti Lookback 

A term/expression, supposedly of Caribbean origin, to describe the following gesture: when a sexual partner lying prone (face down) cocks his/her head to look back over his/her shoulder at the partner behind. The expression on the face of the party looking back should roughly indicate: "Oooh, Daddy, I like that." Agoutis are squirrel-like rodents without tails that make a similar gesture due to their anatomy.

I was hitting that booty from the back like a champ when she gave me an Agouti Lookback. Damn, that was hot.
