Ships passing in the night 

A sexual act involving two consenting adults that advances masturbation to the pinnacle of possible techniques.

In order to perform this act, each participant must sit on their non-dominant hand until normal sensation subsides and then commence to pleasure the genitals of the other participant.

Correct execution of this artful technique delivers the sensation of being twiddled by somebody else, by somebody else, by somebody else and by somebody else.

Nick her in the passing 

To have a casual sexual encounter. Analogous to "Give her a portion" and "she'd do a turn"

Gary: "Dave, I think you have a thing for Gail"

Dave: "Nah, not really, I might nick her in the passing"

Passing Nick Kristof in the Aisle 

To lay a fart in someone's face while passing them in an airplane, bus, subway train or other public conveyance where they are denied a means of easy escape and have to take the full blast directly or at least danger close. From an unfortunate incident in late 2019 when two-time Pulitzer Prize winner and New York Times columnist Nicholas Kristof took such a hit while on a U.S. transcontinental flight.

What happened to you?
I tripped on my shoelace while passing Nick Kristof in the aisle to my Calc teacher on the way back from the Mathletes Jamboree and now I've gotta wear this leg boot for 3 weeks.
Yeah, karma can be a bitch.

pissing in the wind 

Doing something completely pointless which has absolutely no chance of working or being in any way effective.

Trying to fix this fridge with a screwdriver I might as well be pissing in the wind!

pissing in the ocean 

a futile attempt; an act which will have very little or no consequence; a very small proportion of the whole

Trying to stop illegal downloading by arresting individual college students is like pissing in the ocean - there is no way they can arrest millions of internet-users.

pissing in my cheerios 

this is used as an alternative way to say that someone ruined the moment or your day.

"check out this girl I went out with last night, isn't she fine?"

"Ehhh, she's not all that"

"Damn bro, thanks for pissing in my cheerios!"
