Boom's answer was very close. it means that the wheel axle is turning faster than the engine.
This requires a very high gear and is used for good mileage or speeds over 100 MPH.
The the 1950s and 1960s "Electronic Overdrive" was a very cool feature. Basically it was a small two speed gear box off the tail shaft of the transmission. This "second transmission" was electronically actuated even if the car had a standard transmission. Those cars usually has 4 speed transmissions and over drive could be used in 3rd or 4th to give extra gears.
Newer cars have similar features, but in some cases it is simply a 5th or 6th gear that makes the wheels turn faster than the engine. Some of the Nissan and Honda automatics have a feature that works like the overdrives of the 1960's but i'm not sure how it is implemented, it is now all enclosed in the transmission.
My old 1968 MGB-GT could be retrofitted by simply taking off the drive shaft and adding the overdrive unit and shorter drive shaft, then hooking up the switch.

OK, this trigimp dude almost got it right. The older cars had OD that could be used in any gear. Now, your transmission to engine RPM ratio is normally 1 to 1 at the drive shaft in high gear. When you shift to overdrive, this ration changes and the drive shaft will turn 1.5 times to every 1 turn of the engine. That ratio can vary. The OD is ran by what's called a sun gear and 2 planetary gears. They can be damaged if you tow something heavy in OD, they do not like abuse.

Overdrive usually means that the car is running at full speed which will usually be achived in its top gear.

You are responsible for the wake you make. If wake causes damage on shore, to another boat, or anything else, the boat making the wake is responsible. There should not be boats in a swimming area. No Wake, Slow in a marina area means go slow and avoid situations that could cause damage or injury. Generally this is below 5 mph.

It means that the fuel line to the engine is cut off gradually as you take your foot off the accelerator... so you slow down over a greater distance.

final and lowest gear. not for towing, 4x4, etc. Mainly a speed "holder"...saves gas and engine wear by maintaining lowest rpm's possible.
