a chemical bluff that tricks your tongue into screaming fire when nothing is burning

means the quality of having a hot, pungent flavor that creates a burning or tingling sensation in the mouth.

from From "spice" plus the "-y" and "-ness" suffixes. "Spice" came into English through Old French "espice" from Latin "species," which meant "kind" or "sort" — the same root behind biological "species." In late Latin, "species" drifted toward "goods" and especially the costly aromatic wares of the spice trade, so the word that once meant "a type of thing" narrowed to mean "the expensive flavoring things." The "-ness" ending, an old Germanic state-of-being suffix, then turns the adjective into the abstract quality of being spicy.
