So many latin phrases are in common use, e.g. (that's one too) status quo, terra firma, ad hoc, compos mentis, in memorandum, in situ, ex gratia, the list goes on and on, almost ad infinitum.
I never studied latin but the school-yard rhyme goes
Latin is a dead language, as dead as dead can be
First it killed the Romans and now it's killing me
Not quite true.
The title translates  " We're always in the ****, it's just the depth that varies a bit."
