Shackleford 

The act of shitting in a person’s mouth prior to giving oral sex so as to plumb your shit down their throat with your cock like unclogging a toilet

Diana let me give her a shackleford as a thank you for plumbing her actual toilet pipe

Shackleton 

The sheer enjoyment of men wearing ladies underwear when in the company of fellow men.

Wow i had a top shackleton. Forget the castello moment, that was a real shackleton moment. These lacey french knickers made me tingle with sheer shackleton.

Shackle cruise 

A riff of the term "golden shackle" meaning a wedding band, usually but not exclusively when worn by a man.

To "shackle cruise" is to search a person's ring finger to see if they are either wearing a wedding band, or have the tell-tale impression on their finger that a wedding band is supposed to be there.

Can be done by a woman or man.

"See that hot guy at the bar buying everybody drinks? He's really hot!"
"Yeah, I just shackle cruised him when I went to the bathroom. Let's put it this way, there's going to be a very pissed off wife when that credit card statement comes in."

"Wow, that guy on the weight bench over there is HOT. Wonder if he's gay?"
"I just shackle cruised him and unless he's from a very progressive state, you're out of luck on this one."
