The "jib" is the leading sail on a blow boat (sail boat). It determines your course, therefore is your guide. When someone likes the cut of your "jib" they are telling you that they see a person who is heading in the right direction and that they trust will do the right thing.

It is a jib or fore sail that has a slot cut into it.
