This phrase has a history behind it.
Gaius Julius, paterfamilias of the Julii clan/familia, took over Rome, as a Ceasar, a form of dictator for war times (was there ever peace for Rome? i wonder). We all know his infamous campaigns against Gaul and Germania back in 55-46BC. Most notable is his defeat (unfortunately) at Gergovia, by the Aquitanii war chieftan Versciscentorix, who united the Gaelli under one banner, and his victory over the same adversary, just a few yards outside of Alesia.
Gaius Julius was part of the Triandria. Three ceasars who ruled Rome with an iron fist. After the defeat of Crassus Brutus by the Parthians and the remaining Seleucids, Julius overthrew the second man of the Triandria (Pompey or Pompiius) and established himself as a Dictator.
Now around 40-35BC, and after fucking Cleoparta a few million times, in the Roman forum, the group of people, led by Brutus, attacked and massacred Gaius Julius....the last person Ceasar saw was Brutus, so he told him "Et tu filli, Brutus?", means "You too, my son, Brutus?". He couldnt believe he would betray him.
Brutus expected to receive part of the inheritage, if not the throne of Rome, from Ceasar. When he was informed that Augustus, Marcus Antonius and the bastard he had with Cleoparta, would be the next Triandria, he joined this conspiracy to murder Ceasar. It didnt work for him tho, cuz Ceasar was loved, if not worshipped by Romans...so Marcus Antonius and Augustus faced Brutus's army in the region of Macedonia (outside the city of Phillipii) and defeated them.
End of story, im bored. But im pretty sure polluted didnt know any of those.
