Obligatory Sex Scene -- the sex scene that Hollywood feels is almost de rigueur in any leftish non-G movie
The scene in "When Harry Met Sally" where Meg Ryan fakes an orgasm in a restaurant is only a borderline OSS.

Punchline: "I'll have what she's having."

Origin: "Yer awesome!"

A sarcastic insult generally used when someone or something is very kee. Kee and oss can be used in the same sentence to create more variety and affectiveness.

the "correct" pronounciation of osu, the rhythm game. (with the u being silent).

this word is used often in the place of osu, probably mocking the pronounciation, as most people will probably want to say oh-soo.
my friend: how do you pronounce osu?
me: oss. i know, i don't get it either.

This is the true definition. Don't read anyone else's. We know what we're talking about. We made the word up last year. We don't know where it came from or why it started. It just did. There is an Oss on my fridge. The definition of "oss" is unknown because the word just appeared in our vocabulary one day, but we think it may have to do with a similar word that starts with an "a". Never say osshole though because it makes no sense.
You are such an oss.
