Hall - A type of sensor that requires a power and earth wire in addition to its signal wire, the output is normally a 5v square wave.
High side - A driver that is open circuit when off and powered to 5v or 12v when on.
Low side - A driver that is open circuit when off and grounded to earth when switched on.
High/Low driver - a pushpull or HighLow is an output that is powered "high" (12v or 5v) and switched to low (earth).

PNP - Plug and play
NTC - Negative temperature coefficient, used in context of temperature sensors and refers to the resistance increasing as temperature decreases.
PFI - Port fuel injection
MBT - Mean best timing, used in context of spark timing, it is the spark timing that results in the best torque
MFB - Mass fraction burned, often stated with a number after i.e. MFB10/MFB50/MFB90 and refers to the fraction of the fuel burned by mass.
CR - compression ratio
Stoichiometric - The ideal quantity of fuel to burn with a quantity of air for complete combustion. For gasoline this is 14.7:1, ethanol is 9:1 and methanol 6.47:1

High and low Z - High and low resistance, used in terms of fuel injectors, normally around 14 ohms for high impedance and ~4 ohms for low.
Injector impedance - The resistance of the fuel injectors, see high and low Z
Smart coil - A type of ignition coil that has its ignition drivers (IGBT) built into the coil, this means they only receive a 5v signal to activate.
Primary coil - The primary winding of an ignition coil
Secondary coil - The secondary winding of an ignition coil.

Phrases
Twirling the Iron
Wrenching on your vehicle, often used when changing a tire, but has been commonly used other times when you are doing heavy wrench work.
Green Brown Green
A rally term that that reminds you the proper way to drive. Green is trees or vegetation, which you don't want to drive in, Brown or Black is the road where you want to be, so it's preferred if brown and black are in the middle.
In like a lamb, out like a lion
Term about approaching quietly, then tearing though a closed stage like a beast. Usually credited to John Buffum. But it was probably Tom Grimshaw that actually penned the words to summarize John's philosophy.
