A
slang pejorative derived from “first quartile.” The term is used to
label a person as intellectually deficient by implying that their intelligence (
IQ, competence, or performance) falls within the lowest
25% of a given distribution.
More specifically, quart invokes statistical ranking rather than any measured assessment: to call someone a “quart” suggests they are in the bottom quartile relative to others and are therefore presumptively less capable, insightful, or rational.
Quart was first mentioned on November 8,
2025, by the micro-celebrity Buzzbulks.
