Too much Latin (and French)

In the past two days, I've come across at least four Latinisms and one "Frenchism" that I wasn't familiar with. To wit:

• Homo Homini Lupus
• hostes humani generis
• Post equitem sedet atra cura
• delendi sunt
• Quel dommage

(Capitalization is as it appears on the web sites where I encountered the terms.)

You know what they mean, right?

• Man is a wolf to man.
• enemies of the human race
• Behind the horseman rides black care (some of them don't make any sense even when translated)
• they must be destroyed
• What a pity (I should have known this one)

Now that I look at them all together, I'm struck by how somber and pretentious the collection is. I think I have to find a different set of blogs to read.
