Salve - I go with Salvia (as in hierba de los dioses - Salvia divinorum)
Ave - I use Avy
Thank You - I go with Gratis (Free for Portuguese)
Pater - I go Padre (Padre/Priest/Monk i guess)
and my favorite ones:
Futue te ipsum! Go f*** yourself!
Futete f*** you
and so on....you can come up with your own twisted version...hihi
oh..there is a version in Irish and Gaelic:
Irish téigh transa ort féin Go f*** yourself
Irish Gaelic Téigh trasna ort féin Go f*** yourself
