I am spartacus 

Refers to a scene in the movie "Spartacus" starring Kirk Douglas as Spartacus. After the army of former Roman slaves led by Spartacus is defeated in battle by legions of the Roman army, a Roman general stands before the captured surviving members of the slave army and demands that they turn over Spartacus, or else all of the former slaves will be executed. Upon hearing this and not wanting his friends to be executed, Spartacus stands up and says "I am Spartacus." However, the loyalty of his friends is so great that each of them stands forward in succession, shouting "I am Spartacus!" until the shouts dissolve into a cacophony of thousands of former slaves each insisting "I am Spartacus!" Bewildered and still not knowing which of them is Spartacus, but impressed by the loyalty he inspires in his army, the Roman general has all of the slaves crucified in a miles-long display alongside the Appian Way leading back to Rome.

Thus the phrase "I am Spartacus!" is often used to humorously start a chorus of responses of "No, I am Spartacus" among a group.

Person enters chat room and types "I am Spartacus."

100 other people in the chat room then respond with "No, I am Spartacus!", "I am Spartacus!", etc.

Spartacus: Blood, Sand, and Cock

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!

Tween Spastics 

The escalating sound produced by a large group of tweens. At first, the sound is a light chatter. Then it grows in intensity and the frequency changes to a squeal. Eventually the incoherent ramblings of these little pricks drowns out all ambient background sound until you get a massive migraine.

After my buddies and I walked out of the movie theater we noticed a large group of tweens waiting around for mommy and daddy to come in their BMWs & Lexus to pick them up. Their tween spastics were so deafening that we started to bleed from our ears.
