An English speaker from another country where this does occur can correct me if I'm wrong, but in English, we don't use "x" to mean comparison, we use vs., which is short for "versus" ...I have seen x used this way in Spanish and Portuguese media. In English, x means "by" or multiplication/times: "2x4" (2 inches wide on one side by 4 inches on the other) or "3x faster" (3 times faster) or in math, where many cultures use a "dot" we use x: 5 x 5 = 25
