Hi! I've heard people say １０年早いわ！on various occasions, always on a mocking tone. For example: 私をナンパしようなんて10年早いわ! My understanding of it was something like : you're dreaming ! / you can't be serious ! Is that correct? Recently, I ran across it in a manga in an exaggerated version: 私より目立とうなんて１０００億万年早いわ！(If you think you can stand out more than me, you're sorely mistaken ??) Do people change the number in that phrase a lot ? Thanks a lot in advance!
