It's actually 2 expressions combined, duche bag (- historically known as an instrument of cleanliness bestowed upon a dirty piece of female genitalia) and fag(Short form for faggot aka homo).

This expression is used when a duche male is sleeping with a lot of other men. He's like a male - gigolo, for men!
He's gay, a total duche fucking fag bag!
