After I had just finished eating a cookie for dessert at lunch yesterday:
Friend: Eat that last muffin.
Me: I can't.
Friend: It's yours. Eat it.
Friend: You can't let it go to waste. Eat it.
Me: I can't. I'm too full. Besides, it'll ruin my chocolate chip cookie mouth.
Friend: That might be the gayest thing you've ever said.
