A Newspeak word from George Orwell's dystopian novel 1984, "bellyfeel" essentially means to blindly and enthusiastically accept something or someone.

An airplane that is very capable and will be one of the safest things in the sky once it returns to service. However, all the media want you to know is that it's somehow doomed to be a death trap forever, because fear-mongering and clickbait bring in those oh-so-precious clicks and money.

Politically correct (aka Newspeak) term for "physical distancing". You're not actually distancing yourself socially. Social distancing is actually distancing yourself from society and being less social. We're not doing that here in the midst of the coronavirus pandemic.

A word (or phrase) that has been overused or misused so much that it now has zero meaning whatsoever.

An Elon Musk fanboy/fangirl. They'll often force Elon into many completely irrelevant conversations as that's all they can basically talk about. They are often completely oblivious to the inherent problems in the real world that will cause many of Elon's ideas to fail.

When it comes to engines, the term "deleting" refers to the removal of one or more of the emissions control devices that the engine came with. When an emissions device is "deleted", the device and any other relevant components in question are physically removed and the engine is then re-tuned to run without said device.

"Deleting" is different from "defeating" in the sense that "deleting" refers to physically removing emissions devices, but "defeating" involves disabling emissions devices while leaving all of them in place on the engine. For example, an EGR (exhaust gas recirculation) cooler can be defeated by welding it shut in some spot or blocking it off from one or both ends by inserting a metal plate between the cooler and the exhaust or intake manifold. DPF's (Diesel Particulate Filters) can be defeated by being drilled out or by installing bypass pipes.

On Diesel engines, people who do deletes will typically remove EGR (Exhaust Gas Recirculation) systems and DPF's (Diesel Particulate Filters), as these two systems are infamous for drastically increasing a Diesel engine's fuel consumption.

Diesel Particulate Filter

The purpose of a DPF is to filter out particulate matter (a.k.a. black smoke) from a Diesel engine's exhaust, which consists of two distinct components, soot and ash. Soot is elemental carbon, which is the visible black stuff you see, and soot is the result of unburned fuel. Ash, on the other hand, consists of non-combustible metallic salts and is formed because engine oil contains many magnesium, calcium, and zinc compounds, and small amounts of oil are inevitably going to be burned along with the fuel.

A DPF is typically a big muffler with a ceramic honeycomb inside it that catches all this soot and ash and holds on to it. It doesn't let it out the tailpipe. It works well. But the problem is, it's a FILTER, and over time it's gonna get plugged. And once it's plugged up you now have an exhaust restriction, which is bad for your engine. It reduces your power, and you get all sorts of other problems. So how do you get the DPF to be clean again?

Many engines now have regeneration systems that spray fuel into the exhaust and blow air into it, then they light this fuel on fire so that the DPF can be heated to around 600°C in order for the soot be turned into carbon dioxide. This clears out the soot. Ash, on the other hand, is non-combustible and builds up in the DPF over time. Even during regeneration ash remains in the DPF and at some point you will have to wash the thing out or have it professionally cleaned in order to get rid of it.
