"Claudish", that's a great term, a homophone of "cloddish (adj): foolish, awkward, or clumsy".
Deepseek 4.1 has (unsurprisingly) started speaking with a strong Claudish accent too, throwing around "honest" and "load-bearing" with abandon, and just generally obfuscating sentences with dense and unnatural phrasing. I'd give it a longer prompt in AGENTS.md regarding my preferred tone, but I don't care for wasting tokens adding an extra translation layer on all output (caveman mode costs tokens trying to chop everything down)
