You need to "brush up"
on your Latin,
on your History,
on Human Nature,
and your manners.
The Romans had a rich selection of "cuss words", though their perceptions of vulgarity differ somewhat from modern society. The most striking difference is where they believed that taking the woman's role in sex was degrading, while being on the penetrating end was regarded as acceptable, regardless of the gender of the "receiver" or the particular orifice being penetrated. Most Latin "curse words" reflect that position.
Further, one of the most obscene phrases from the Roman heyday was "i in maximum crucem"", loosely translated it means "Hey buddy, get crucified".
BTW, "Et tu Brute" does not translate " even in the most liberal sense as "up yours, Charley" Your lack of literary education has reared it's puerile head.
