👉 The slang word you've mentioned is '519509.1268491139; (2E) 3(furan 2yl) 1(4 methyl 2phenyl 1,3thiazol 5yld 1one)' can be thought of as a bizarre mixture of chemicals and molecular structures.
Example sentence: "Your chemist's assistant has been working with this strange concoction of chemicals from faraway planet Mars. The mixture is so peculiar that it's causing all sorts of problems for your chemistry experiments, making them run wilder than ever before." This term is a blend of various chemical components (including the bizarre '519509' which appears to be derived from Mars), and its unusual properties (the 2E and 3 at the end indicate that it contains an unknown compound). The term is often used to describe something that is unpredictable, mystical, or even fantastical.
