Litmus Piss 

The initial test pee after getting into a swimming pool to see if it contains a urine-indicator dye that turns the pool water blue or cloudy, thus indicating the location/catching people peeing in the pool.

Shortly after getting into my boss's pool, I squeezed out a litmus piss to check to see if that bastard added a chemical to the water. Once I was in the clear, I then diluted out the chloride by pissing all over and slowly swimming away.

litmus text 

A text you send your significant other to find out if they're still pissed at you from the night before or after a fight. The text is usually a short and simple-worded text like "hey" or "hi"

I got in a fight with my girlfriend last night so I sent her a litmus text to see if she was still pissed

Litmus Fart 

A small sample of gas expelled, often in a large crowd, in an effort to ensure that a larger flatulence experience can occur thereafter without detection.

Because I had sauerkraut with dinner, I had to fire up a litmus fart at the bar.

Litmus Test 

The act of covertly sniffing a finger that has been inserted into a woman's vagina while making out for the purpose of determining if it is safe to proceed to oral sex.

I was going to munch her box, but I ran a litmus test, and it came back positive for stank, so I just bagged it and tagged it.

Litmus Pussy

When you are unsure whether or not you have an STD, so you fuck a chick and tell her 6 months later that she should get checked out because you may have an STD. You then use her test to see if you have an STD.

Debby was the best litmus pussy ever. She got checked out the day I called her.

litmus test 

The act of following a questionable male or female to a public restroom to determine his/her actual gender.

"Chris" wore clothes that either sex could wear, had a haircut considered tolerable of both genders, and a voice that's indistinguishable between an angel or a scruffy Southerner. So Joe did the ol' litmus test and followed Chris to the office's bathroom.

Litmus Jest

The joke a comic will tell about a subject before deciding whether or not to launch into a five minute bit about it. Coined by Peter Moore.

They laughed at my litmus jest, so I knew it was ok to tee off on 90's rappers for 10 minutes.
