What does battier mean?
"Battier" is the comparative form of the informal adjective "batty," which describes someone or something as eccentric, irrational, or mildly crazy. To say that one idea, plan, or person is battier than another is to say it displays a greater degree of harmless madness or absurdity. The word belongs firmly to casual register: it appears in everyday conversation, humor writing, and light journalism rather than formal or clinical contexts, where terms such as "irrational" or "delusional" would be preferred. Its connotation is generally playful and affectionate — describing an endearingly odd uncle or an increasingly outlandish theory — rather than harsh or stigmatizing. The underlying term "batty" emerged in the nineteenth century, most plausibly inspired by the erratic flight of the bat, and it pairs naturally with expressions like "going batty." "Battier" is useful precisely because it allows gradations of craziness: things can grow battier over time, or one notion can be judged battier than another.

Etymology of battier
"Battier" derives from "batty," a British and American slang adjective first recorded in the late nineteenth century. The term is widely thought to originate from the bat, whose swift, erratic flight suggested mental instability, though some sources connect it instead to the dialect word "batty" meaning a butter churn or to the phrase "bats in the belfry." Whatever its precise trigger, "batty" settled into common use as a mild synonym for "crazy," and "battier" arose as its ordinary comparative inflection, formed with the suffix "-er."
