A drinking game in which any time a spoken or visual reference to blood, sand, or cock appears, all players take a drink.
References can be changed or added at any time for the slower and more dialogue-heavy portions of the episode, as long as the drinking continues. For example, references to tits, amputees, or any time someone says a word that ends in -us can all be added to the further the liquor consumption. Synonyms for any of the three words -- such as "dirt" or "shaft" -- can also be used as references.
Spartacus: Blood, Sand, and Cock example:
Lucretia: "Oh, Jupiter's Cock!"
Me: Cock! She said cock! Everyone take a drink!
