Catullus 16:

I’ll push your shit in and stuff your face–
Aurelius, you cocksucker; Furius, you little bitch–
since you think that my little poems
have gone soft and I must not be too upright!
It’s true; the devoted poet should stand erect
in his values, but not necessarily in his little
poems, which are truly witty and charming
when they’re a little soft, and not too stiff,
but can still cause a little tingling–
I don’t just mean for youth, but for hairy men
who can’t make their own loins stand upright!
You! You read about my “many kisses”
and doubt I’m fully a man?
I’ll push your shit in and stuff your face.

Edit: This is Catullus’s poem written in response to two of his critics. He essentially told them “I will rape you in the ass and mouth, you faggots” in the first and last lines. For those wondering, the latin translation of that is “Pedicabo ego vos et irrumabo”
