nasal-ingressive voiceless velar trill 

Linguistics joke. There's a fake IPA symbol to go with it, that looks like a pig snout.

It's linguistically correct description of, well, the sound pigs make.

First-year linguistics students can be humiliated by asking them to include nasal-ingressive voiceless velar trill in their presentation of rare and difficult-to-pronounce sounds in the West African languages.

Ingre's Violin 

Refers to the French neoclassical artist Jean Auguste Dominique Ingres, who while famous for his paintings was also incredibly talented though less well known for his skill on the violin.

The phrase refers to a person who is known for one talent but is so exceptional at another unrelated talent they could be equally well know for the second if not for the first.

Everyone knows joe is a great baseball player but his work as a photographer is a bit of an Ingre's Violin.

Ingress 

The most addictive game ever made. Do not start playing unless you're prepared to play constantly. This is a 'capture-the-flag' augmented reality game created by Niantics Labs that poses two different 'factions', the Enlightened and the Resistance, against one another to battle for portals that are GPS synced with public landmarks. Enlightened players are green and referred to as 'frogs'. Resistance players are blue and are called 'smurfs'. Besides being the most addictive game ever made, it's also a great way to meet other people who are also addicted to the game. The only positive lure about the game is that it will teach you about your surrounding areas and educate you about the history of where you live.

"I'm not addicted to heroin anymore, because now I play Ingress."

The Ingram Effect 

To come to a realization that your current state (physical, mental, emotional, etc.) depends if you would of done something different long before now. Similar to the butterfly effect, but a lot less chaotic.

Andrew: "I wonder if I am this hungry because I decided to get a small fry instead of a large fry last week."
Tiffany: "You know what's that called, right?"
Andrew: "Me making a dumb decision?"
Tiffany: "No, silly! It's called The Ingram Effect!"
Andrew: "Hmm, so I didn't notice this before, but I got a small cut from the barber a few days back. Something like that?"
Tiffany: "Exactly!"

incrementalism 

The slippery slope that often causes generally principled people to slide into unethical behavior.

Although we have all come to understand that the Fraudster in Chief has no internal ethics compass to begin with, it seems more likely that many of the lifelong public servants who wound up in his thugsphere fell victim to what philosopher Jonathan Glover describes as the following process: “Incrementalism is how we slide into participation by imperceptible degrees so there is never the sense of a frontier being crossed.”

ingrediences
