Literally: Read Only Memory.
ROMs are games that you can use on downloaded emulators. These games are usually licensed. A lot of good ROMs (unpopular games, games exclusively released in Japan) can be quite hard to find, knowing how most sites give you a ton of bullshit and forced voting, but no ROMs. Emulation and ROMs are the only way I have access to great Japanese SNES games such as Super Wrestle Angels, YuuYuu Hakusho Tokubetuhen, Sanrio World Smash Ball!, and Super Puyo Puyo 2 Remix.
I opened my Snes9x, opened the Super Wrestle Angels ROM, and began to play.

Read Only Memory derivative. Office speak (IT slang) for people who will never "get it". Like a ROM chip you can't write to, they cannot have new thoughts, they only spew back what has been programmed into them. Unable to write to their brain.
