Three Questions About The Disney Sitcom - K.C. Undercover "K.C. Undercover"- One of the Disney sitcoms I like. Here are 3 questions I want to figure out. I hope someone can help me. :) 1. In the first episode, K.C. need her mom's permission slip signed for her field trip. And she said:" No slip, no trip. No trip, I flip." What does "I flip" mean here? I just know "flip" = "turn something over". 2. Marisa, K.C.'s best friend. She asked K.C. to a prom on Friday night. But K.C. said:" Tonight is a school night". I'm not sure the meaning of "school night". Does it mean students still need to have classes at night? Don't laugh, I really don't know... ;-) 3. K.C. thinks that she looks like an idiot when she's talking to boys. That's why she refused the asking. She said:" I just come off sound like a complete idiot." What dose "come off" mean? That's all my questions. I know, too many questions are disturbing. But I still expect your feedback. Have a good day! Everybody. ;-)
