Learners sometimes use "perplexity" in very casual speech where "confusion" or "I am confused" sounds more natural. Also, some confuse "perplexity" with "complexity": "complexity" is about how complicated something is, while "perplexity" is the feeling of confusion that this complication causes.

Another mistake is using "perplexity" for any kind of error rate; it is a specific probability-based measure, not a general word for all model errors.
