What constitutes a trashy novel?

I always thought the answer was gratuitous sex scenes amongst shallow characters, but others have told me it's an insignificant plot.

I Googled the answer and (palpitations!) it brought up chick lit. Chick lit! Surely not. Other answers are a formulaic book written for scandal or simply a badly-written book. It seems no one really knows the true answer. Maybe it's an easy-reading book that you've enjoyed?

When I brought up this question with a group of writers, a gentleman answered: ‘Any book written by a female.’

Yeah, I know, idiot, and not because the group was mainly made up of women. So the question is still out there—what constitutes a trashy novel?

Meanwhile, my own trashy, chick lit novel (with no gratuitous sex scenes or insignificant plot) is now free in the Amazon lending library. Feel free to check it out:

  

A Proper Charlie

 What’s a girl to do when she discovers her boss is a wanted man?

Amazon

She's losing her job.
She's losing her boyfriend.
She can only afford to eat spaghetti hoops on toast.
She's called Charlie... Charlotte, ginger, ginge, Duracell or carrot.
Yet with all these odds against her, she pushes forward to take the lead story on her paper at London Core.

Shame no one knows.

Shame she's the office general assistant and not a real journalist. Shame it's on missing prostitutes and Charlie thinks pretending to be a 'tart with a heart' will get her that story.
She doesn't just get a story.
She becomes the starring role.

 Unashamedly trashy!
