These are now magic items in my headcanon. 🤘🏼 Spelled "Piece o' Scrolls", and first invented by Tau Teeno the Impatient. Their somatic component is a very, very small (ie. "micro", even) gesture with a flat palm as if in greeting/farewell, and a short but shrill vocal "eep" to finish.
The resulting effect can vary between casters, depending on the spells' ingredients, but the most prevalent are surprise tiny napalm and long-lasting bowel disruption.
A certain country once fought an entire war against these "large, flightless bird"s, and lost —despite superior firepower, including truck-mounted Gatling guns. 🤷🏼♂️
In the same vein, falling flat on your face is technically forward progress. Technically. Take the W, and pick the gravel outta your teeth. 🤷🏼♂️😅
