One thing I always loved when taking Latin in school was how succinct the insults are. Are you an idiot simply boils down to stultus es, a common insult was fur meaning thief which in practice was used for many circumstances. My favorite was bustirape (pronounced Boos-te-ra-pay) which meant grave robber, but roughly translates to lowdown son of a bitch. Maybe it was because they had to chisel so much of their language into stone, but the Romans really were champions of brevity.
