I came across the word "chap" while reading the book The Rules of Life by Richard Templar. It occurs in the sentence
But then all my problems are object related and needs practical solutions - a chap's sort of thing.
It is in the chapter "Rule 58: Know when to listen and when to act". From the sentence, it seems that it is a name of a profession, but cannot get which one.
According to the Cambridge dictionary or the Urban dictionary, the word "chap" has several meanings: a synonyme of guy, or a gentlemen, or a homosexual (acknowledging it or not). None seems to feel in this context. The closest is "guy", following the cliche that men need action and women need talking about problems, but it doesn't fit with the chapter (as well as the whole book) that doesn't have any gender-related content.
What is the meaning of chap in this context ?
