Here are some examples:
* "That's just great!" (said sarcastically when something bad has happened)
* "I'm so excited to be stuck in traffic." (said ironically when someone is frustrated by the traffic)
* "This is a real treat." (said when something is unpleasant or undesirable)
Irony can be verbal, situational, or dramatic, and it's often used in humor, literature, and everyday language.
