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.

5-0 Lookback

Verb: The act of driving past a speed trap, then looking in your rear view mirror to see if the police are chasing you.

Even when I am driving under the speed limit, I always do a 5-0 lookback until my heart rate is back under a 100 bpm.

"The Lookback" 

A euphemism for the sexual position crassly referred to as "doggystyle" or "from behind." When it comes to making special requests in the bedroom, "The Lookback" resonates with spousal ears better than any of its synonyms. And it's functional, too: the name implies a finer point of receiving cock in this particular position--literally looking back and showing the guy a little face during the action--and it will accordingly serve as a reminder to girls.

"Hey Veronica, wanna do doggystyle?"
-"Ew, Archie, NO! I am far too classy for such trailer moves. Try it out on Betty instead!"
"Ok Ronnie, I apologize. Can we please do "The Lookback" ?
-"Oh, Archie-kins. I thought you'd never ask!"

"Hey Mom! what's a lookback?!"
-"Well honey, um, it's when a man and a woman love each other very much and.. the one who's getting on a plane to accept the big job the new city looks back wistfully at the other."
"Oh. The school maintenance guy told me it was something different."
