Yes, let's define "loser".

A "loser" is someone who loses.

They could be Tim Tim nice but dim, qualified as a solicitor, decent chap - his practice is going under and he is going bankrupt.

Or they could be Wayne Jobless - not only can't get a job but can't even make a successful benefits claim and sanctioned into starvation.

A successful crim is not a loser.

A successful thug is not a loser.

Johnny prisoner with 3 babymothers ready to smuggle contraband in is only partly a "loser".

Those are not the attractive forbidden boy. That forbidden boy is the archetype from Lawrence's "Virgin and the Gipsy", the drug dealer with god teeth and diamonds drinking Grey Goose and Kristal, even maybe Mark Thatcher the clueless but very rich arms dealer. The people who stick two fingers up at society's rules - and at a girl's mother telling her to keep her hand on her ha'penny.
