Learn English – “Try me”: Too Sexually Suggestive and “Slangy” for Retail Marketing

If someone 'provides too many details on something actually making it difficult to get the needed information out' a word that could be used is 'verbose'. This is an adjective which means too wordy or using too many words as in a write-up or a speaker addressing an audience.

Please see my comments below first.

My second offering: circumlocution (n.) - the use of unnecessary wordy and indirect language. The adjective is circumlocutory. An antonym of a circumlocutory expression would be a forthright expression.

I'd be surprised if this hasn't been asked on this site already, but this is a rather contested idiom.

First, the order of the phrases is uncertain. If the idiom was derived from the phrase, "You can't eat your cake and have it to," as some have suggested it would make much more sense. If you ate it, you no longer have it.

Second, the verbs accepted today a) may not have been the original verbs used or b) may have had different meanings. In some early mentions of this idiom, "eat" is replaced with "ate."

Third, depending on your understanding of the structure, the current phrasing may be fine. If I said, "You can't have your cake and then eat it," then of course this makes no sense. I believe this is the thinking of most people bothered by this current phrasing. If instead you view the verbs as having to occur concurrently, then the idiom makes more sense. By eating it, you no longer have it. As you eat, the less you have.
