Cool is an aesthetic of attitude, behavior, comportment, appearance, style and Zeitgeist. Because of the varied and changing connotations of cool, as well its subjective nature, the word has no single meaning. It has associations of composure and self-control (cf. the OED definition) and often is used as an expression of admiration or approval.
