Misflung

Slings and arrows, Bingley, slings and arrows quite misflung.

No assessment, evaluation, or reified label on their misflung ball.

Like being summoned by the Headmaster for a mis-flung flint.

That a rock had dropped from the sky, barely missing the boys, an act of God or a misflung projectile or an attempt on their lives or merely a pale tutor's flight of fancy.
