Polite sarcasm refers to using a sarcastic tone that doesn't come across as hurtful or mean-spirited. It's an art form that can be difficult to master, but when done correctly, it can add humor and wit to conversations. Some synonyms for polite sarcasm include dry humor, subtle irony, gentle ribbing, and tongue-in-cheek remarks. With dry humor, the speaker uses a deadpan delivery to make a joke. Subtle irony makes a point indirectly, while gentle ribbing is teasing in a playful manner. Finally, tongue-in-cheek remarks use sarcasm to say the opposite of what is meant. All of these forms of polite sarcasm can be used to poke fun at a situation or person without causing offense.
