This is so funny to me, coming from the kpop/k-entertainment fandom where it's known as "Manner Hands" and is seen as very respectful and considerate of the girl's personal space; gallant af. Not using Manner Hands can cause a huge stupid scandal so almost every idol does it and after red carpet events there are always these gushy news articles praising someone's FLAWLESS MANNER HANDS LOOK AT THAT SHOULDER-AVOIDING TECHNIQUE HE'S SUCH A PRINCE 10/10 WOULD HUSBAND

Not trying to hijack btw, I second the prompt as-is, I just think it's interesting how something nervous and awkward in one culture is the HEIGHT of gentlemanly conduct in another.
