1. An ability to enjoy or say things that are funny. My dad had an amazing sense of humor. He'd always have us in stitches whenever he started telling one of his stories! I was just joking, for crying out loud! Don't you have a sense of humor?

2. The part of one's personality that determines what specifically one considers to be funny or appreciates as humorous. I've got a pretty weird sense of humor, so bizarre comedies like these are right up my alley. Slapstick has never really fit with my sense of humor.
