Idioms

[AoM]

hoc habet (Aen. 12.296)

L&S says it's gladiatorial terminology for a wounded fighter (i.e., "he's hit").

Though I guess it's more of a colloquialism.

 

[Cinefactus]

buxo pallidiora Ovid Met IV: 134-5
paler than boxwood

 

[Pacifica]

I'm not sure that's an idiom.

 

[Pacifica]

I'm also not sure what's so funny.

 

[Pacifica]

You're infuriating.

 

[Pacifica]

 

[Cinefactus]

I'm not sure that's an idiom.

The note in one of the books I have (Henry T Riley 1889) said that it went on to become an idiom. It does say some other things though that I am not convinced about.

 

[meisenimverbis]

The only one that comes to mind (always) is "lupus in fabula", I'm sure someone must have brought it already (sorry, I haven't read the 18 pages...). For some reason I like this one.
