Here are some curse words in Latin
- Faex – shit
- Deodamnatus – damnit!
- Cunne – Cunt
- Filius Canis – Son of a bitch (dog)
- Fututus et mori in igni – Fuck off and die in a fire
- Futuere – Get Fucked
- Futue te ipsi – fuck you
- Ede faecum – eat shit
- Morde meum globes – bite my balls

This kind of thing is always hard. For example, futuo does mean “fuck”, but it’s generally used of a male on a female, and it’s not really a negative thing. But running with it anyway:
-
Wrong. faex is the root of the English “faeces”, but in Latin it just means the dregs or sediment of something.
-
This has been made from deo + damnatus, so “condemned by god”, but I’m not convinced that it would equate to the English “damn it”.
-
Correct. landica would be even more obscene.
-
Almost correct, but since I assume you’re calling someone this, it needs to be fili canis. (You can’t really do anything other than call people names like this without knowing how the words work).
-
“Having been fucked, and to die in a fire”. Get rid of et and change mori to morere or moritor.
-
Correct.
-
This assumes that the English “fuck you!” is using the imperative, which I don’t think it is. It’s more like a kind of weird subjunctive-y thing. At any rate, this would probably be understood as “fuck yourself”, which is nice. Needs to be ipsum, though.
-
faecam is not a word. It’d be faeces, and wrong (see 1).
-
Should be globos meos morde, and I don’t think globi holds the same connotations as balls. Try coleos.
-
Same problem with futuo.
-
Literally, the closest English word is actually skullfucker, but it does have the same insulting sense as “bastard”.
-
Correct.
-
Should be facio.
-
Fine.
-
Correct. (Literally correspondent to the English “working girl”).
-
Correct.
-
Correct, but the word order would sound weird.
-
obscenum vile (possibly unless you’re talking about a male prostitute, in which case obscene vilis, but I’m not sure at all on this one).
-
mundus stercoris would work better, and this is quite a creative one. Literally “a universe of shit”.
-
See 9.
-
Correct.
-
Correct, though the problem of connotations is especially apparent for this one.
-
Correct.
-
See 7.
-
“Your head is in an old woman”? I’d go with in culo.
-
“Perish!”, as an order given to multiple people. Problem is that it’s not really that insulting. Also happens to be the word for “skilfully”.
-
Correct.
-
Correct.
-
Correct.
-
scronium does not appear to actually be a word…
-
Correct.
-
Almost, but needs to be vocative, obese porce.
-
Should be fututor.
