When looking for an alternative phrase or term to use in place of "screwing around," there are a variety of options to choose from depending on the context. For example, in more formal or professional settings, one could use phrases such as wasting time, procrastinating, or lacking focus. For a more casual setting, one might say goofing off, messing around, or slacking off. Other possible synonyms could include fooling around, dilly-dallying, or simply not staying on task. No matter which term is used, the underlying message is clear: the person is not being productive or using their time effectively.
