What's "non sequitur" mean?

Native speaker’s answer

"Non sequitur" is a noun that means a statement that doesn't logically flow from the previous one or is not clearly related. Here it's used for comedic purposes or attention, which then might make sense further in the conversation. Ex: We were talking about vacation and when she gave a non sequitur about her past. Ex: Sometimes, he uses a non sequitur to change the conversation topic. We'll be talking about projects, and he'll ask about dinner.
