I'm guessing 180 is 180cm, as 183cm is 6ft which fit's in to the whole "don't swipe if under 6ft" meme. Which, in case you're unfamiliar with it, is a popularised (no idea if it's actualy popular) line on dating app profiles where you swipe to indicate interest in talking. Which somewhat demystifies the rest.
