Original Equipment Manufacturer.

OEM software is what you get "bundled in" free when you buy a computer. It might include Windows, some complete older programs, "taster" versions of new programs, etc.

OEM stuff is unsupported and comes without manuals or any kind of help. It's a free gift, take it or leave it.

Buying second-hand OEM software can get you a real bargain, as long as you know enough to get by without the manual or support.
When I bought my new computer, they gave me five OEM programs free.

Acronym for Original Equipment Manufacturer

It's just another way of saying "stock." The parts that come standard on anything: Cars, Computers, boats, planes, electric tools, ect. just to name a few.
Just get the OEM brake pads; they may be stock, but they work fine.

Stands for "Original Equipment Manufacturer." This refers to a company that produces hardware to be marketed under another company's brand name. You can also use the term as a verb, such as, "That Dell monitor over there is OEM'd by Sony."
For example, if Sony makes a monitor that will marketed by Dell, a "Dell" label will get stuck on the front, but the O.E.M. of the monitor is Sony.

That should impress your friends.

Obnoxious Egotistical Motherfucker

Someone who is just the world’s biggest self-serving, attitude-filled pain in the ass.

And it's safe for office environments since only select few will know the true meaning behind your use of it – like FYI.
- What do you think about John?
- He’s an OEM.

That OEM up in Accounting.......

WTF has happened to Bill? Was cool at first, now just another OEM.
