"Lovey-dovey" is often used to describe couples who are excessively affectionate or overly romantic in a cheesy way. However, if you're looking for other words to describe this kind of behavior, there are many synonyms to choose from. You might use "mushy," "sappy," or "schmaltzy" to convey a similar sentiment. "Cutesy" and "adorable" could also be used to describe couples who are lovey-dovey, without the negative connotations. Alternatively, if you're looking for a more light-hearted way to describe this kind of behavior, you could use "smoochy" or "huggy-bear-esque." Whatever word you choose, just remember that everyone expresses their love differently, and what may seem excessive to some can be perfectly normal for others!
