What Does 'Guilty Pleasure' Mean?
A guilty pleasure is something that you enjoy despite feeling slightly bad about it - in other words, something that you shouldn't like, but like anyway. Guilty pleasures are usually relatively harmless things that don't tend to have a negative effect on anybody else; in fact, the "guilt" is usually just a fear of somebody else finding out, as guilty pleasures tend to be mildly embarrassing.
