Curing Cramps a la Korean

I have been watching quite a few Korean dramas lately and I often see something rather strange practised time and again by some of the drama characters.

I am talking about touching their tongue with their index finger and then their nose, they do this a few times.

Currently I am watching Reply 1997, a very good coming of age drama which I can highly recommend.

One of the boys had a girl sleeping soundly with her head on his legs.  Instead of waking her up,he started licking his index finger and then touching the tip of his nose several times.

I google about this strange thing and came up with how to cure a cramp a la Korean.  It figures then that the boy had a cramp from the weight of the girl’s head across his legs.

I will try it if it works the next time I get a leg cramp! 😉
