Quote from Will in The Fresh Prince Project
Ashley: Well, I'm glad I'm good at something. I tried out for the school chorus today, but I didn't get in. Will: How come? Ashley: Well, when I auditioned for Mrs. Berkley I couldn't remember all the words to the song. The part I remembered was fantastic. Will: I'm sure it was. I bet you're def. Ashley: That's what she said. Will: [chuckles] Not- Not deaf. D-E-F. That's just slang. Means terrific, good, you know. Ashley: Oh, well thank you.
