hand-wavy

Dismissively imprecise explanation

Hand-wavy describes explanations or arguments that gloss over important details, relying on vague gestures rather than rigorous reasoning.

The term evokes someone literally waving their hands to distract from gaps in logic: His proof was hand-wavy at best.

Common in technical and academic contexts where precision matters.

Also hand-wavey.
