jabberwocky

This term carries a whimsical yet critical tone, often used to describe language that mimics the structure of a real conversation or technical document but lacks any actual substance. It suggests a deliberate or absurd obfuscation, evoking the feeling of a puzzle that cannot be solved because the pieces are fake.

Because it originates from a specific literary poem, the word often implies a certain level of intellectual playfulness. It is less harsh than calling something "gibberish" and more focused on the surreal or fantastical quality of the nonsense.
