Chull Meaning

chull or chul is something that is disturbing you, not the sad kind of disturbed that is. The word was used literally for an itch, but then in the present day its figurative meaning became more popular. As in, when someone has an itch to do something, or have something, a sort of craving, it's called chul.

In the song 'kar gayi chul', the line means that the beautiful girl has given my brains an itch, a craving, that I have become crazy for her.
