"Laugh off" is a phrasal verb that means to dismiss a situation, comment, or accusation by treating it as humorous and not taking it seriously. Synonyms for "laugh off" include "brush off," "shrug off," "dismiss," "ignore," "deflect," and "make light of." When someone laughs off something, they are not willing to engage with it seriously and instead try to downplay it by making a joke out of it. It can also imply a lack of concern or interest in the issue at hand. While it may be appropriate to laugh off certain situations, it's important to carefully consider when humor is appropriate and when a more serious response is required.
