Clean Eating

I think it entails different things to different people.

For me, it means no processed foods, no sugars (except from fruits), I don't drink anything except water, lots of veggies, fruits and lean meats.

I hope you didn't eat that cake that you have in one of your profile pictures then.

Others have already stated that this phrase is ambiguous at best.

Generally accepted practices that fall under the heading include the following but are not limited to:

Actually purchasing unprepared foods and cooking them to prepare a meal. (prepackaged quick fix meals loaded with sodium and preservatives do not qualify)
Moving away from stuff loaded with Hydrogenated or partially-hydrogenated anything, moving away from fructose corn syrup in most any form or name.
Including a variety of colorful fruits and vegetables in the diet.
Moving away from bleached flour and cutting back the starchy carbs in the diet to varying degrees. This is a fairly obvious consequence of the previous point when budgeting calories. When you increase something, something else gives way.

Hope that helps.
