Oejo is a person who doesn't date their friends. It's not that they don't date period, but they don't date their BFF's because they don't want to cause drama. Usually an Oejo does this because they've dated someone in their friend group and it ended badly.
"That Oejo doesn't date anyone because he dated his friend."
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
