I slapped a Korean friend on the back, and he said, "때리지 마" and something about spicy.
I thought i heard him say 손 or maybe it was 손가락...and the verb 매워.
I asked him about it, and he laughed and said "don't spicy finger me!".
I'd like to reconstruct what he actually said in Korean. Anyway, I'm not understanding the spicy reference.
Is there an idiom about hitting someone and making them feel spicy?
