Wait, the sound caused the grass to catch fire?!
As an example, its intensity (in W/solid angle) is 14 orders of magnitude (AKA 100 billion times) highter than the 80 dB people usualy use as a safety limit.
Sound that loud wouldn't just kill you, it'd rip you apart.
Saying a burrito is "quite spicy" usually means "surprisingly" but not "excessively" or "extraordinarily".
Those things are already too subtle and hard enough to learn in a second language. People defining the same expression with widely conflicting meanings in different places do literally turn it into a maze :)
