When we describe something as "a pathetic/poor/sad excuse for something", we are essentially saying that it falls terribly short of expectations and is unworthy of consideration. Luckily, there are many synonyms we can use to convey the same sentiment. Instead of using these phrases, we can describe the situation or item as being "unacceptable," "unsatisfactory," "substandard," "unsuitable," or "insufficient" instead. We could also say that it is a "lame," "pitiful," or "feeble" attempt at something. Regardless of which word we choose to use, it is clear that the situation or item is far from being adequate or deserving of praise.
