O&S

O&S is the abbreviation of the duo bosses in the game "Dark Souls", Ornstein and Smough, whom guard the Chamber of the Princess in Anor Londo.
This abbreviation is used by lazy people, whom don't bother writing the full names when looking up guides on how to beat them.

The O&S bossfight is sometimes referred to as the hardest and douchiest boss battle in the game.

Nick: Stop screaming Dan! What are you doing?!
Dan: O&S are fucking annoying as shit. Ornstein fucking stabs me, then Smough rapes me with his hammer!
