rubber check

Where a gal promises to "pay" you for a favor by spreading her legs for you afterwards, but then unexpectedly insists that you wear a condom, which of course drastically reduces the pleasure of the act and thus largely negates any true value of said "payment".

Any time that a "willing" chick offers me sex in exchange for my assistance, I always make sure to first ask her if she's gonna let me "do it bareback" before I decide whether or not to bust my ass for her --- oh, I might still help her out even if she wants me to use protection, of course, but I still like to know what I'll be actually getting out of da deal --- I've gotten too many rubber checks in da past!

function check

A function check is a military euphemism for male masturbation, as if to compare the penis to a weapon.

Private Duffy, perform a function check on that M4 rifle.

Yo man, I’m so horny I’m going to go perform a “function check”. If you know what I mean.

canary check

Taken from the times miners had a Canary down in the mine shafts to detect deadly gasses, this is a check of a toilet after destroying it with your bodily waste to make sure it's clear.

"I'm just gonna use the loo."
"Hang on. I was in there. Let me give it a Canary Check."

Vibe Check

A “vibe check” is a casual or informal way of assessing or evaluating the mood, energy, or general feeling of a person, place, or situation. It can also be used to determine if someone’s attitude or behavior aligns with the group’s energy.

“We walked into the party, and the vibe check was positive—everyone was having a great time! and passed the vibe check!”
